The SES comes on occasionally. Ive had the s/c coupler replaced..u-bend removed... i know its well over due for a tune up with 125k miles but it just started outta no where...it used to like chug when u gav it light steady gas but i put a fuel injector cleaner in it and it stopped a few k miles later it did it again i did the same and it didnt stop and evenutally did this...please help!!!!!!

ALL SUGGESTIONS AND OPINIONS WELCOME

I answered your other thread too, start with a tune-up: plugs, wires, air filter, fuel filter, PCV, then see what happens. If it doesn't help, then let us know and we can point you in other directions.

well what bout another 500-600 after the first one?

blazindave · #4 10-14-2005, 08:52 AM

try starting a few more threads about it - it just might help...

What other information can you provide that may be helpful. Is your GTP stock or modded. Do you have a CAI or K&N drop in filter?

If you can get it to where the SES/CEL light stays on, get it scanned and see if there are any odb-ii DTC error codes. Codes of interest would be any misfire P030X, MAF sensor or throttle position sensor (TPS).

Does the SES light ever flash when the problem occurs?

The reason why I raised the SES light flashing is unless the PCM is braindead, 99.9% of the time a real misfire condition will cause the SES light to flash then go on steady. Then a P030X code should be stored which can be retrieved with a scanner. If you have an Autozone or similar nearby take it and get it scanned when the SES light is on.

The SES light is the most tangible fault indicator you have for now without it being a guessing game or wasting money on parts that may not fix the problem.

When was the last time the tranny was serviced....ATF and screen filter? Check the condition of the fluid and make sure it's not burnt. It should be a reddish color not brown or black. Sounds like you're getting excessive slippage.....torque convertor or clutch. You might have to get it to a tranny shop. Plus they can scan it and see if any DTC error codes are present. Certain tranny codes will trigger the SES light too.

One thing you might want to check is the speed sensor on the transmission. I know this is a little far fetched but it can cause problems that are often mistaken for misfires or other engine problems. I don't know if this will correct the problem but you might give it a try to see what happens. It may just help!

Cbierniat · #11 10-16-2005, 01:56 PM

If it had something to do with the transmission wouldnt it shift sluggish or funny? Cuz it shifts gears fine it just shakes and shimmys when i give it over 1/4 throttle...i put some more fuel injector cleaner in it and it runs a LITTLE better...but ive had myc ar since 94k miles and ithas 125k miles and i have not changed anything besides the oil, airfilter, and oil filter maintenance wise

BNaylor · #12 10-16-2005, 02:24 PM

Other than telling you it still sounds like a misfire condition as suggested don't know what else to tell you. Do you know where the MAF sensor is located? It's the black module with electrical connector on the top of the throttle body. Disconnect it and take it out for a spin and see what it does. If it doesn't change the symptoms just reconnect it and try the other suggestions above.

Also have you checked into the possibility of a fuel system problem. How old is the fuel filter? Plus you can check for proper fuel pressure at the fuel pressure regulator. Good luck!

Without the codes here I don't think any of us, although everone here is try to help, should go any further with this, it's more like hand holding. Not butting in here, not judgemental, but as you read thru the posts this is what it seems to boil down to.

I agree. However, whether he wants to make it easy or hard which includes getting the PCM scanned is his problem, although it has already been suggested. I would have done that a long time ago. In the meantime everyone will probably continue to weigh until he gets totally confused. We can suggest but he has to execute and provide feedback.

I went to autozone b4 when my car was messed up and my engine light was on...they gave me some code that had to do with my o2 sensor but when i took it in to a real shop they scanned it and said it was the supercharger coupler...so im not sure..ill go and get the code from them and get back with you guys thanks for you patience if i had some free money id get it fixed but im only 20 and just started my new job
