The best thing to do would be to check for codes, (ground the number a and b pins in the diagnostic connector maybe with a paper clip with ignition off stick one end in a and the other in b and turn ignition on), it will flash I believe 3 times 1 and then 2 which is ok, and after that it will flash a different number of times count them and then reply as I have the codes. If it is doing that there should be a code even if the engine code light does not come on all time maybe a code 43 which is the Spark Control Module, This is NOT the module inside the distributor.
This module is what causes the vehicle to die when at idle at times.
I do hope that this will help you out friend.
I'm not a whiz on the current dashboard electrical ... but I believe it's based on a Flex circuit PCB that connects to all the gauges ?? Anyway - As multiple gauges are going bad all at once - I'd check the most common thing first .. The Ground to the Dash panel Circuit ....
With engine running and radiator cap off, when the thermostat opens do you see any bubbles in the radiator?
Has anyone else had this problem? If so, what was your solution? Have you had any luck getting the system repaired? If so, what did you have to do to prove the failure and get it fixed?
Several mechanics have told me that the problem is caused by the ignition, and will need to be replaced. However, I have opted to put up with the issue rather than replace it. I'm not so sure if that would fix it either, and I am not willing to spend the money to find out.
Good luck in resolving the issue. I've been dealing with it for over a year now. It is the most irritating when it does it in the morning on the way to work. . .

While replacing the plugs, wires and distributor cap, I discovered a leak in the gas tank. I decided to pour in some gas and try running it a little just to see if the previous problems had been fixed. They hadn't. I couldn't even get it up to 55 mph.
I did some research while waiting for a new tank to arrived to find out what could be the problem with the rough idle and the acceleration. I replaced the gas tank, but now the thing won't even start. It makes me worry that I've got bigger problems. Will replacing or cleaning the fuel filter, injectors, catalytic converter, vacuum lines, etc really fix the problems. I don't want to spend more time and money on this truck if it's a lost cause.
In my case I always have more time than money. Therefore when I'm trouble shooting I try the inexpensive things first. Have you checked the code read out yet? How's the MAP sensor? You mention off road, did the tank have water in it. Replacing fuel filter sounds like a good idea regardless. My S-10 had a leaking vacuum line to the PVC which reeked havoc on idle and shifting. You didn't indicate what the vitals were, like oil pressure, compression check, condition of transfer & transmission. All things being equal, I would recommend at this point don't give up the ship.
Good luck,

I'm thinking there's air trapped in the system. My rig's not overheating, the coolant is new; replaced the hoses and thermostat less than 6 months ago; no leakage since gaskets replaced.
Was wondering if you had this problem and if so how did you solve it. Right now I'm dazed and confused :confuse:

Good luck.
Will be doing this myself. Had the vehicle in twice (once for the initial repair & back to have the air removed) and still have a slight sloshing / bubbling effect. Plus can put a decent squeeze the upper hose and somewhat on the lower and hear coolant gurgle a little.
Am going to pick up a pressure tester.
Thanks for the link
Is there any chance that there is a blockage in the heater core ?? A Restriction may cause it to require excessive time to fill/ "squirt through" and fill the core causing the sounds you are hearing ??
I'm not sure where you are Geographically - but (again a long shot) - Could trapped water in the air conditioner drain pan (from outside water - or air conditioner condensate usage) be part of the noise you are hearing ???
Good Luck - and let us know what you find !!!
Torque Converter problems ?? - was this Tranny/converter EVER taken out before ?? (http://www.txchange.com/tcinstal.htm)
Or #2 - Cracked Flywheel ...
Both, I'm sure, you do not want to hear - but Try Surfing the net for vibration problems (ie, Torque coverter vibs, Flywheel vibrations, etc ...)
I hate to pay a dealer for anything - but sometimes you drive in - the tech take a look / ride and immediately says - oh sure, I get a lot of these and it's always XXYYYZZ. If he's right - it's worth the diag fee and beats replacing - or just pulling - parts/trannys -"just in case" ..
Let us know how you make out !!!
Please help! I love the truck, even with all of the issues I have had that are all well known.
Thanx for the reply.
b/o luck

Also - Did you check for a "Bent" or Warped rim ???

I have a question about an issue I seem to be noticing every so often. Sometimes, when I go to start it the truck kind of hesitates as the pulleys go for the first coupke of turns. To better describe it, its almost as if it does turn and then holds for a couple of seconds and then turns again and starts. It hasn't not started yet. I've already changed the sparks plugs. At first it only did it after sitting overnight but then I noticed it happening after a long commute.
Anyone have similar experiences or ideas?
Specs: 1999 S-10 4cyl 2.2 5spd 76K :confuse:
I'm not savy with Cardan joints in drive shafts as to what characteristics makes them good or bad. When I took the drive shaft out to change out the drive shaft carrier bearing all joints seemed ok to me. Also I didn't see any evidence were it lost a weight. They don't put zerk fitting in drive shafts anymore.
Thanx,

1. Recently my check engine light came on and is staying on. In the past it would shut off or I would disconnect the battery to reset the computer and it would shut off. Of course every time I take it to be checked out, the light goes off and the mechanic can't find out the problem. It doesn't even register the problem in the computer. I will try to got to the mechanic again this week to see what they can find. Any suggestions
2. I have recently heard a mid-tone constant hum coming from what I believe is the fuel pump area. It is mid-tone and will sometimes go to a high pitch. Any suggestions
3. Any suggestions for maintence I should perform with 48,000 miles to increase the life of my truck. The only things I have done are ( I bought it with 24,000 miles) are regular oil and air filter changes as well as the serpentine belt replaced.
Any help or suggestions would be greatly appreciated
