Ok so my 91 RS camaro service engine light goes on only sometimes and it runs very badly like it has no power to it and sometimes the RPMs even get up to like 4500 and only sometimes at a stop light when im stopped it will just bog out but if i turn my car off sometimes and restart it the light will go away and itll run like a champ anyone have an idea what the problem could be??? Plz help

 

First step, get it scanned and post the the trouble code here. There are alot of guys that can help you from there.

 

That is pretty stupid...lol
