thanks
I think most Chevy Dealers will do it for free.
If its not the radio anti-theft device than it is probably an engine code that needs to be cleared. Of course you will need to buy an expensive scan tool or go to the dealer.
Good luck, let me know how you make out.
As for your service representative, sounds as if he's trying to pass the buck. You may need to go over his head to a sales or business manager.
Good stuff and Adobe PDF allows you to search the entire manual for keywords.
You rock. I'm a mygmlink.com user but never found the Owner's Manual PDF. I much prefer the electronic copy both for searching and for the fact I don't have to go out to my glove box to look something up. Thanks a million!
I would first do a tire rotation, and see if the vibration changes in nature. I'm betting it does, and that you will find 1+ tires are defective.
P.S The fan works it just makes a terrible squealing noise..
Sounds like last year, whoever worked on the car chose to just replace two parts instead of fixing the actual problem. You can diagnose a thermostat problem versus a sensor problem. Of course if they did the work cheap, and good, I guess you can look at it as maintenance.
When any electrical work is done on a car and the battery is disconnected, the ECM looses all of its learned air/fuel maps, along with a thousand other operational parameters. As you drive the car, the ECM re-learns the correct amount of air and fuel to give the engine so that it idles smoothly, with low emissions, at the right RPM. (It's learning other things too, but lack of idle re-learn is what caused your stall.)
You'll find it runs better and better in the next days. Just how long does it takes to get back to normal? It's a fancy formula on just how long it takes to 100% re-learn and for every sensor to reach "ready" state... based on time, miles, speed, A/C operation, temperature, and more. Just be patient. If a while goes by and the problem comes back, then raise it up at the dealership.
Any other ideas besides the computer re-learning? And a week after being at the dealership, is it suppose to be stalling again? Mind you, he drove it for that whole week and only had one other time were it seemed to be a harder start during that week; no stalls.
:lemon:
Once you get over this hurdle, it wouldn't surprise me if you have many more years of hassle free driving.
Would have been much cheaper than throwing all these parts at it!!!
It really is too bad to be in your position, but especially since you have invested so much TIME and MONEY I wouldn't walk away now. I would FIGHT the dealership to get the problem resolved. Every manufacturer makes some lemons - it's sad, but true. Ford, Nissan, even Toyota with its Camry transmissions have had serious problems over the past year. It's how the dealer works to fix things that is absolutely not right!
Ask them why they have not hooked up a data recorder?
(They may call it a laptop with data scanning ability.)
Ask them why they don't diagnose the problem instead of guessing and changing parts?
:mad:
My personal money is on a defective replacement PCM. Of the parts you list, only two could cause a sudden, complete stall: the PCM and the crankshaft position sensor. The CPS is not very fancy, not much can go wrong with a new one. PCM's on the other hand are sensitive and tied into a lot of wiring. If for some crazy reason they won't give you a data recorder to drive with (for FREE OF COURSE) they ought to try and put a new PCM in for you. Still shooting in the dark, but it's the most likely target.
I've got almost 98k on my 2000 Impala, and the only time it has left me stranded has been when the battery has gone bad (knock wood!). My Impala experience has been comparable to my previous Toyota experience, so I'm very pro-Chevy/Impala. I wouldn't blame you for considering a Toyota or Honda next time, but I'm not so sure you'd be doing youself a favor by going to Daimler-Chrysler.
How did you resolve your situation??
