Engine sputter
Hi guys, so I just bought an 07 cobalt ss/SC about a month ago and it has had some issues fRoman the time I bought it. It does seem to have a stage 3 kit from ZZP but I haven't gotten a chance to see what all the car has done.
Anyways, the problems I'm experiencing are the car sputters sometimes in between gears and also everytime when I hit about 4-5k rpms in every gear. Also, some days it will randomly just stall out at a red light when I try to go in 1st gear and then when I start it back up, it will just try to stall out and the rpms try to drop so I have to over Rev just to get it moving. But then 30 min later it will just run "perfectly" fine (as in as it normally does).
If anyone can help me determine what it could be, it would be appreciated! Thank you

Cam, what do you mean when you say your car sputters in-between gears? You say it also sputters between 4-5k RPM, does it sputter over 5k RPM? Then you say 30 min later it will run fine, does the high RPM sputter also clear up at that time?
Mrbelvedere do you think he should be throwing a lean code or not necessarily? I have never had a bad filter with my car.
