Need Help! My Car idles rough in drive and park.
My car runs rough from time to time in idle when in drive or park. No check engine light Ever! other then that the car runs great . When i start to accelerate its a little choppy especially after the car has been running for a good bit and when its either hot or humid. then after i get past 12 1300 rpms then it's back to normal. I think it might be an EGR problem but im not sure at all. Can someone help?
My Car 1999 Camaro SS LS-1 346ci ALL STOCK 67,000 Miles I purchased it with 60,500 miles and have owned it for exactly 2 years. Thanks in advance!!! |
I have a Diablosport programmer that can scan for codes and watch some of the sensors while it's running if you want to check the car out. I actually have a spare EGR as well if you wanted to try it for testing.
|
yeah that would be great actually!
have you heard of this problem before? |
It sounds similar to an EGR problem but could be something else like plugs or wires. My car ran like that after I did the header install and forgot to put plug wire #8 back on the plug! :mrgreen:
|
yeah, just weird cuz i have no mods
|
pull a plug out and see what they look like...the car may have sat for a while before you bought it and could have fouled plugs.
|
The sensors in the MAF might be dirty, or you need new plugs. When is the last time you changed the plugs if ever?
It might also be a shot O2 sensor, but I think you would throw a code for that. |
thanks guys def appreciate your help , if anyone has anything more to add please let meknow
|
i have the same prob... only happens at low idle and when the cars hot. like at a stop light it will lurch forward and the settle down.... weird
|
thats EXACTLY my problem !!! GRRRRR
|
Choke issues?
|
Does the check engine light come on when you first start the car? If not, then the bulb is prolly bad you may actually have codes.

the check engine light does come on
|
yes it does... has never thrown a code either

when i said the light comes on i just meant at start up then turns off, so i dont know if the scanner will bring anything up.
|
If there are old codes they might still show up. And if there are any not ready conditions they will show up as well.
|
bump
|
for those who said there take a look at it or scan it i just got my car back on the road today so whenever any of you can let me swing by the would be great! the sooner the better .
Thanks |
If you want to stop by after work one day or over the weekend we can scan it and you can try swapping the EGR if you want to see if that eliminates it.

Hopefully that vacuum leak was the only problem. How was it running after driving it home and giving it a chance to clear itself out? It was interesting watching the computer try to compensate for the extra air getting in and then going into limp mode to balance it back out. I'll look for the replacement pcv valve part # I grabbed for my car.
