I want to trade it in on a Toyota truck!
Very strange problem you have if it only shows up when towing a boat! But then in this post you say "it only does it when towing, mainly". That "mainly" kind of says it is not just towing problem. It might show up worse when more power is required from the engine but you might have it going on at all times.
Does your engine have the aluminum heat shields around spark plugs? My 04' Tahoe does (or did).
I had a problem with misfire severe enough to put service engine light on when the spark plug boot was not installed correctly on the plug (not deep enough) and the spark shorted through the heat shield to engine ground. Shields in my Tahoe have a grounding springs in the end of them that prevents spark from forming between shield and engine.
When I removed the grounding springs I could see faint sparks between several heat shields and cylinder head.
With grounding springs removed I tried two sets of GM spark plug wires and two third party sets to try eliminate the spark between heat shield and engine ground with no luck. It seems that regardless of the spark plug wire set some spark leaks through to the heat shields and a spark shows where the shield is close enough to engine ground.
If you have the heat shields take them out and see if it helps. Your spark plug boots will get hotter but they will not burn away immediately. If you get help doing this then do what I did: Go purchase a good set of racing spark plug wires that do not need to use heat shields.

It took a few weeks for them to respond with copies of several pages each for each bulletin.
O.K. Last night I was on the interstate and I was going about 75, I passed a motorcycle, on a hill and while on the hill, the light came on and started flashing, but I felt no vibration, or shaking. After the hill, it stopped flashing but stayed on. Now today, or soon, as before, when Im driving around on regular roads, the light will go off I bet. I hope Im not driving everyone crazy with this, thank everyone for reading these and trying to help though. I almost have the damn thing payed off ( 1 more payment) and it is acting worse and worse. A mechanic told us it may be a bad injector or stuck valve. Maybe a #4 new injector would fix it?
Swap #4 injector with another cylinder injector to rule it out as a problem.
I wouldn't think the injector is the problem. I don't believe that the computer in the car knows if fuel burns in a particular cylinder or not but it can know if your spark is not right. Someone correct me if I'm wrong with the above statement.
It didn't come clear to me if you have those aluminum heat shields around spark plug boots?

Since taking the intake off is such a pain in the [non-permissible content removed] (off a chevy truck) it will be easier just to put a new injector.
( instead of taking intake off, swapping it, putting it back together, see if that fixes it, then if it is the #4 injector, taking intake off again, putting a new injector on
Seems like just putting a new one on would be easier. I bet that wont fix it either though.
I don't understand what you mean by it being easier to put a new injector than to swap two of them. By swapping I mean you take that #4 off with say #3 and then install #3 to #4 location and then #4 to #3 location. I don't think you need to remove intake for this. Fuel rail removal should be enough.
But first, take that heat shield out from that #4 if you know which one it is. Taking them all out for sure rules the shield spark leakage out as a problem if you still have the problem without them. Very simple test to do and could completely fix your problem.

weekend, what a Pain......
I am also having Remote Door lock Problems, Any help would be appreciated.....
Thank you
How did your fuel pump go out? Did it just quit or did you lose fuel pressure with pump still running?
Do you think your gas mileage went bad because of the new pump?
You could have a fuel pressure regulator problem. If fuel pressure is too low fuel will not spray correctly thru injectors. This for sure would mean worse gas mileage.
Have your fuel pressure checked and have it done at different location than where the fuel pump was replaced to get true answer. Hope they didn't have your fuel pump replaced when you might have just a regulator problem.

You idling and dying at stop lights problem could be caused by many things other than the fuel pump. Usually whe a fuel pump goes bad your engine won't even run. Your problem could be a dirty fuel filter, or even electrical related (plugs, wires, timing, etc) or possible fuel injection related. Take your Tahoe to a good garage with a diagnostic center and let thme pinpoint the problem.
I take my Tahoe to the dealership and tell them they can have this [non-permissible content removed] car that I dont care what do with it. I told my service adviser that I want to speak to his mgr. We are all sitting in small room, and I let lose! I first said I know that they have done everything they can, I dont blame them but GM.
Now they know I'm piss and they hand me a ck right there for 1.000.00 I told them that I cant except the money because I'm going to my lawyer. He tell my that the ck is only for all my inconvience. I call my lawyer @ the time he tell me to take it. I tell the service mgr that I suppose to take my daughter to Mammoth for a week, I had to cancelle because I cant trust this car.
So I leave the dealership get home to call GM to start a case #. Well they call me on Friday and tell me there nothing they can do. That it is the user and not the car.
I will let you know what happen in court! :mad: :lemon: :lemon: :lemon: :lemon:
If GM said to me right now we will put you into a new Tahoe I would go for it, but there not. I will keep you updated on whats going on. I do know its going to take sometime. I only hope everything happen before ski season. I snowboard all winter in Mammoth. I cant trust this car to take it there. My daughter is 15 she and I are the only one who go down there. Anyway I have to get ready for work take later.

I had "Service Engine Soon light come on my 99 Tahoe with 71,000. I took it to a private mechanic and the dealer. Both said I need for them to go and and pull the heads and clean and re seat the valves. The dealer said it was because of poor quality of gas (not enough cleaners in fuel now) I'm pretty upset with GM 71,000 and had to have a valve job done. It cost me $1600.00; this may be my last American Vehicle. So does anybody know good fuel additive on the market?
Any advice on how to improve gas mileage?
Check out the Fuel and Oil Additives discussion.

Sounds very strange that a service engine soon light tells the mechanic and the dealer shop that they must pull the heads and clean and re-seat valves. Never heard of such before. (I know for sure there is no code saying they need to do that.)
If you have the service engine soon light come on and that would be caused by VERY dirty valves you would have all sorts of engine performance problems like very rough idle. Valves dirty that bad that it sets the code would require build-up on valves to be so severe it would not allow valves to close properly.
Sounds all BS (sorry my language) to me but perhaps you had all of the problems with engine performance that you really had very severe build-up on valves.
Right now, based on what you posted, I think you were hosed off of your money. Sorry to say that but it seems like more than half of the repair shops INCLUDING dealer shops just want to make a quick buck on anybody they can and bill you for work that they do not even do. If you don't stand next to your vehicle when they work on it you have no way telling what they do or don't do.
After seeing what my Chevy dealer did or didn't do when my new Tahoe had problems and I had to fix it myself when it was under warranty I can not trust anybody with car shops any more. Luckily I can fix almost any problem on my vehicles or at least diagnose what the problem is so I can protect myself a little bit better than an average car owner but it just scares me to think how people who can't do that are paying so much money for work their vehicles don't need.
I'm sorry if my comments make you loose your sleep over your money as you might have been hosed quite bad. But as I said, perhaps you did have all sorts of engine running problems and had really dirty valves.
If these shops would really have wanted to help you they could have told you to try some fuel additives first to clean your engine valves. This of course would not have generated any business for them.
Go ask your private mechanic what kind of relationship he has with your dealer shop.

I need to show this to court judge b/c a cop gave me a ticket indicating that I went over 100mph, when there is no way my SUV can ever go over 100mph due to factory speed limiter.
Thanks for any info.

Here's another, non-Chevy, link
Anyone have any service manuals or factory bulletins indicating what the factory top speed is?
tidester, host
Slow down and read the second link again:
"Acceleration from 0 to 60 mph is a relatively decent 8.7 seconds but top speed is a lowly 98 mph."
Thank you for your reply. I had my vehicle put on DX computer twice both came up the same result. The dealer may in fact put to me. I had get engine fix so I could get smog-ed. I agree some dealers sometimes take advamntge of customers or have ill trained techinics that don't no what they are doing.

Many thing can affect your mileage: quality of gas, the way you drive (quick stoplite starts, flooring the pedal to pass, etc) how fast you drive (usually the faster you go the less your mileage) state of engine tuneup, amount of air in tires, rear end gear ratios.......all these things affect mpg. Make sure you are not comparing apples to oranges when you compate your mpg with other vehicles.
So I would like help with resolving this problem too.
I was wondering how you made out with the dead battery problem. I bought a Z71 Suburban back in 04 and have been having the same problem every since. The dealer says he can;t find the problem. Did you have any luck or answers?
Go to an auto part store and buy a can of A/C compressor lubricant. It sounds like your compressor is running dry and that is why it is making noise and wants to seize up. You also need to have a service port hose to have lubricant added in the system.
Procedure is very simple and could fix your problem. Compressor making noise kind of says it might be ready for change though.
About metal scrap in the system it is very possible that you have metal shavings from the compressor in the system but there is a screen (at least in all cars that I have owned so far is) at the expansion valve. This very fine screen should catch pretty much all metal shavings that come from the compressor.
The other thing that catches shavings is the dryer that is also located in the system before the evaporator coil. You want to change dryer and expansion valve at the same time if you need to replace your compressor.
The quoted price of $1700 sounds way too high to me, but I'm used to work on these systems myself and don't even think about taking my vehicle for service like this. You just end up paying for something you don't need.
Of course, if you are not a hands on person you may need to pay for it but I'm sure someone else will do it for much less than $1700.
Compressor might cost a bit though but you can always find a rebuilt compressor from auto part store that is as good as a factory new one. Cost might be up from $300.

Interested in what Consumers Union, a.k.a., Consumer Reports found when they did a random dealer purchase and fuel economy test of a 2002 model year Tahoe, 5.3L, auto trans?
CITY - 9 MPG
Overall - 13 MPG
I put this over here for u so u can see what is real world. U are getting real world for the 5.3L Tahoe. Your MPG is normal.
I get about 14 MPG O/A.
If I can help any one the all of you help me please let me know.
Thank you for letting us all know the end of your story, which was kind of a happy one when you was able to save a considerable amount of money.
So many people posting here don't say a word about it. The trail of a problem just stops. Often it might mean (I hope) that this forum gave some help in fixing a problem but so many don't bother letting others know what really happened.
Thanks to you!
