Still waiting on California to respond to a real and definite fix for this dilemma.

The $10 for 24 hr. access could be useful for those who would like to perform their own maintenance/repairs. I'm not sure how cost effective this would be over the long run compared to purchasing printed copies of the repair manuals.
It is just not going into gear correctly in 1st, 3rd & 5th. Could it be that the clutch is not fully disengaging or maybe something in the shifter? I don't think it is internal to the transmission, because the things I have done seem to make a difference.
Anyone have any ideas on what I should try?
Thanks

This is a 4 cylinder, 5 speed, manual transmission pickup with approx 99,000 miles.
It started running a little rough on acceleration, so Toyota dealer cleaned fuel injecters and adjusted valves. Now the truck sounds like a tractor when it runs and idles very poorly. They say it is just fine and no problems, but maybe will need a timing chain one day, but I'll know if that happens (how will I know that?). What I don't understand is how these two services that should have improved performance actually made things worse and why they won't acknowledge any problems when the truck sounds so awful.
Second problem, which I wasn't really aware of, is they tell me clutch is getting weak and will need replaced shortly. They say that clutch has to be almost released entirely before gear engages. The thing that I wonder about is that I have all of my service records from time of purchase of this truck brand new and this clutch has never once even been adjusted, but now they say it needs to be entirely replaced. I have heard that clutches can be adjusted. Is that not the case with these Toyota trucks?
Yes, obviously, I'm a girl and know very little about vehicles, so any advice will be most appreciated. Thanks in advance!
Possibilities- air cleaner cover/ductwork not properly sealed (will give a throaty sound to it), bad exhaust manifold, piping, or seal; bad idle control solenoid (affecting idle).
Regarding the clutch- if your clutch is operated by an hydraulic master cylinder (sometimes referred to as an hydraulic clutch) it is mostly self adjusting. Look on the firewall to see if you find a reservoir that looks a lot like a brake master cylinder reservoir, but that is not the brake master cylinder. (The clutch master cylinder will not have the big round "can" vacuum booster that you have with power brakes.) If you find a clutch master cylinder, it's likely that the clutch doesn't need adjustment (there should also be some reference in your owner's manual). 93K miles is not bad service from a clutch disc in any event. Cost shouldn't be outrageous unless this is allowed to go on so long that it damages the flywheel.
I would not normally bring the clutch problem to a dealer, unless you're lucky enough to have found a svc dept that you have the greatest confidence in (like I have w/ the local Pontiac/Saturn dealership here). Find a good general mechanic shop with a lot of good references from friends, and see what they say. Perhaps get his opinion BEFORE committing to any repairs.
Good luck.
Let us know what the dealer says.
When I accelerate from 0mph, at any speed of acceleration, I hear a knocking noise centralized (at least from the driver's seat) somewhere under the bed of the truck. I read other's posts about a knocking noise, but nothing near or under the bed. As if a bolt is loose, or something. Originally, it occured only when braking, also at any speed/rate of braking, which is still continues to do so. This happens, when accerating or braking, a good 9 out of 10 times. Annoying. Before I turn it to the dealership, please don't let me turn it to the dealership, any possible solutions or suggestions?
Thank you.

I'll look in to your advice and appreciate it all!
You'll know you fixed the problem when you accelerate gradually and ease into overdrive, the transmission will shift smoothly and RPM will drop. Fixed my 89 but cost almost $900 for all six new injectors. I did the work myself with a friend on a Saturday morning, by 1PM all was fixed.
In Germany, where that work was done, the Toyota dealer there had never had a car in their shop with injector problems. Obviously clean fuel and autobahn speeds clean things out!!
Good Luck
Any thoughts or ideas.... please help!!!
I just returned from the Toyota dealer when having a similar problem, except mine is a horrible squeak. Putting in the clutch stops it immediately, but while in neutral or in gear you can hear it loud and clear. They told me it's a tension pully on one of the belts directly beneath and to the left (facing the truck) the engine. I was told it needed to be taken off and oiled. While I was there, he sprayed WD40 on it while trying to identify the noise and has since made it twice as bad.
Looks like a job for this weekend.

I need to install an electric brake controller for my trailer. The truck cane with a pig tail that plugs into the wiring harness for this purpose. The problem is the wires are a different color than the electric brake controllers on the market. I Spent 80 bucks on a controller and shorted it out by connecting the wrong wires. I've talked to 2 dealers and they were useless.
Does anyone know the combination?
Thanks
The other lights that come on are: The front parking lights, the light that lights up the dashboard as well as the rear license plate light. I thought the problem might have been from a crossed wire from an aftermarket tow hitch wiring harness that had been installed. I removed the harness and all the wires associated with it, and re-taped the wiring. Still the lights continue to come on. The truck also had an aftermarket alarm system. A "Code Alarm Vehicle Security System", model 707 Plus 4.0. I removed the alarm and all its associated wiring, but still the lights continue to turn on. I even purchased a Chilton's repair manual with the hopes of tracing the wiring but the diagrams on these books nowadays are skimpy at best; it doesn't even show the wiring for the headlights! I remember their older books, they used to have pretty thorough diagrams. I guess not any more! I've disconnected just about everything, including taking the instrument panel out, disconnected all wiring leading up to the column to the light control unit. Disconnected the dimmer switch and still the other lights continue to come on. I hope someone can help me solve this problem.
Thank you. ";
You might have some luck if you post it on another board in Maintenance and Repair (I think), called Got a Quick, Technical Question? (I think).
Re wiring diagrams - I wonder if the electronics on modern cars are so complex that they're harder to draw up.

Anyway, a few days ago I was driving on the highway at about 55 mph or so, and my truck just died . . . I mean just flat out and immediately died. It went from running great to not at all in a split second. It turns over (seems like it's turning over fast) but that's it.
Now, I am absolutely NO mechanic, but the cousin who picked me up on the road that day told me that it could be the timing chain, but that was based on him having broken a timing belt on a little Hyundai hatchback...not a real good comp, but he said that was exactly how his vehicle acted.
Then, I went to speak to another distant cousin who is a pretty good mechanic, to see if he felt like looking at it. He is pretty much retired, but I thought he may want some extra money. When I told him that the truck was a Toyota, he was a bit iffy, but when I replied to his question of engine size by telling him it was a 6 cylinder, he said flatly "No", that he didn't want to fool with a Toyota 6 cyl. We had been talking a bit about what he thought was wrong with it, and when I said "6 cylinder" and got his reply of "No", he immediately said "Ask D.M.'s son...he had a Toyota 6 cyl that did that, and they fixed it". Well, it turns out (and I told him) that the truck I was referring to here was THAT exact truck, as I had bought it from D.M.'s son...he said, "Well, call him up...he can tell you. It seems like it was something to do with 'the computer'".
So, I called the old boy up, and he told me that he had had trouble with the truck twice like that. Once, there was a "ground wire" loose on "the computer", and that a fellow near here had fixed it. He didn't know where this "computer" was at, only that he recalled the fellow fooling with a "red wire" near the battery...or so he thought, anyway. His best recall.
Let me interrupt myself here by again stating I am no mechanic, so forgive any screw ups in terminology, etc. I am just trying to repeat him as close as possible and as best as I can recall. If what I say makes no sense, it is only because I don't know enough to recognize that.
The second problem he told me he had had was one where "a pin (shear pin/wedge??)" that held the timing chain sprocket started to lose integrity and would allow the sprocket to turn on it's shaft a bit....this would cause the truck to screw up a bit here and there until it finally came all the way loose, and it again stopped running until fixed".
Well, I asked around again about the location of this "computer" and was told that it maybe "under the passengers seat" or "behind the glove compartment". I ordered a Haynes manual so that I could at least locate this "computer", and all I could find that seemed to be anything remotely like that was something that was not in the "Engine Electrical Systems" section, but in the "Fuel and Exhaust Systems" section, and it was called the "ECU". It is located, according to the Haynes manual, as being somewhere near the firewall on the passengers side. The way it is shown, however, I simply cannot tell exactly where it is, because it is drawn inside of a ghost image of the truck, and I cannot tell if it is in front of the firewall or behind it. When I pop the hood, I surely don't see what I can ID as this ECU, so I assumed it had to be inside (which would concur with the guy who told me that it was "probably behind the glove compartment"). There is a bundled cable that gathers from the engine area and goes through the firewall, and to me this would also seem to make me think that this wire bundle was heading toward this "computer"/"ECU".
So, I pulled out the glove compartment, and I see, obviously, a good bit of some sorts of electrical components, wires, etc. There is a small, angular squirrel cage blower back there, and a "tin colored" metal box on the right panel that I can see the top of peeking out of the bottom plastic molding. That metal box looking thing, maybe an inch and a half thick or so, if that, seems to be MAYBE the thing that is labeled as the "ECU" in my Haynes Manual diagram, but that is a guess. Finding it may do me little to no good anyway, as I am not sure what, if anything, I can do anyway.
Now, I am planning on leaving Friday and taking a weeklong trip, and I am find someone to fool with the thing while I am gone. But, in the meantime, I was going to scratch and grab a bit, especially if it possibly really is something as simple as a "loose ground wire on 'the computer'". As I said, I am not a mechanic at all, but I am not a total idiot either, in that I can kinda take instruction on this sorta thing. I am surely not a stranger to working with my hands. Again, without sounding like I am trying to oversimplify this, I am simply wondering if anyone out there has any hints that would be feasible for me to check out or look into. An example of this type of thing is a question thatmy brother and I posed to this very forum (under the unsername amosmoses1 (I think)) concerning a Lumina with AC blower problems. It turned out that it was a "vaccuum actuated switch" problem, which I easily found after being told what it may be (rats chewed through a vac line, believe that or not). I just thought that someone may have had a similar problem and could at least give me a heads up on what it could be. Simply, any and all advice would definitely be greatly appreciated.
The only other thing that I could possibly add, which may not be even remotely related to this but I still want to throw in here, is something that happened about 6 months ago to me in this truck: I was heading home from a buddy's house about 100 miles from my home. I got on the Interstate, got up to about 70 mph, and did something rather unusual for me, I turned the blower on. I have AC in the truck, but I was always one who rolled windows down. I don't recall if I was turning on the blower for AC, for defrost or wahtever, but the truck started running rough as hell. I thought it was gonna die, and it would kinda kick on and off. It was related to the blower, but I didn't realize that at first. When I cut the blower off to listen to the engine better, it stopped, which made me make the correlation. It seemed to be worse at higher speeds and only, or mostly, on the "high" blower speed. It seemed like maybe it did it less or stopped doing it on the next to highest blower speed, but I can't really recall....being so farf from home, I didn;t wantto do anything but get closer to home. I intended to look into it later, and this may sound crazy to people out there, but I never did. I just forgot about it until now. It may have quit doing that, or I may have, as strange as this sounds, never have used the blower (at least on high
If you get help, please post.
Thanks, DaSH126
Also the motor emblem on the dash, lite up ( check engine ) what could this mean??
Thanks for the reply. cos289
I asked the man what was wrong and he did not give me a straight forward answer and pretty much said that he had no idea. I asked if this was a recall and he informed me that it is not a recall. He did tell me that Toyota told him that they had switched companies and were using a different transmission and were having problems with it.
Anyway, I was wondering if anyone else has been experiencing these problems and if so what have they done.
Just to let everyone know. I do not know a whole heck of a lot about vehicles and this is also the first time on this site. I have already found it helpful.
