I have an 07 ss/sc with almost 37,000 miles on it.

Occasionally when I start it up even if its warmed up already the idle goes up and down up and down for a little while then smooths out.

Does or did anyone ever have this problem before?

If so how do you correct it?

 

Do general maintenance to it. Clean the maf sensor, throttle body, new plugs, new fuel filter, clean air filter or replace it. That will solve your problem. It's more then likely a dirty throttle body or maf sensor.

 

i had this when i put my exhaust on first...i cleaned the engine bay and it went away....idk how that helped but it did

 

cmcallister - you probably had a lose vacuum line somewhere.

op - general maintenance will take care of the issue, also double check all vacuum lines just to be on the safe side.
