Check with local dealer and make sure your PCM is up-to-date. I did so a week ago and my idoling issues damn near dissapeared. Ask for any updated softwear. It's covered by warrenty. Meaning no charge to you. Also, best bet is to go down to the dealership personally and watch the Servise Adviser input everything. One thing you will need is your entire V.I.N. number (Vehical Identification Number). It's worth it to be 100% sure your car is at its optimal running capacity.

 

what kinda idoling issues were u having? every once in a while when i come to a stop at my house my idol will jump from like 800 to 1500 and back and forth for a few seconds and then stop....

 

thanks for the heads up, they tend to due this on regular matience check ups anyways dont they?

 

^^ Not necisarily.

^^ Mine was doing the same thing. Also, when I would just about stall, I'd cetch it with the clutch and the idol would freak out and bog. But all is well.

 

not all dealers do it unless they are asked/ or there is a problem

 

wait so for my 06 cobalt i would bring it in for a pcm update? b/c i never did anythign to my pcm yet

 

^^^ Yes. I havn't either but there were two updated programs.
