I have a 2007 Cobalt SS and it has a rough idle issue that I need help with. I bought the car in March of this year and it had the issue then (the young Navy girl didn't know what the cause was). I read somewhere on the forum about a CAI (I think that means Cool Air Intake). Maybe that's what the issue is with my car, I don't know. I just had a recall repair done on my fuel tank, fuel pump and a fuel pipe. The car will idle when I start it up now (it didn't before). Once I drive it, it will not idle on it's own (I have to keep up the rpm's or it will die out). When it shuts off, it takes 3 to 5 minutes of constant tries to start it up again (that has been a serious issue with other drivers behind you in traffic) :-(
I really need some help here, if anyone can shed some light on what's going on. I posted this once and I think I put it in the wrong place.
Thanks in advance,
