Yeah car runs perfect after 90*F coolant. It's really weird. Compression is good. Haven't done a leak down yet. Probably should. Occasional missfires if I granny shift it.

2007 cobalt ss/sc stage 2 with 2.90 pulley, full exhaust 200 cell cat, and hptune. Does that only on a cold start when it's been sitting for awhile. Smells like straight up Gas when it does it too. Occasional P0300 and I did get a TPS sensor voltage corallation once and an egr code once P0443. Any ideas? Car seems to missfire somewhat during normal driving. TB has been cleaned, maf was sprayed with maf cleaner, car has been seamfoamed.
But a few things,
I ran a 2.85" on 42s for a while with no problems. I'm on 60s now though.
But anyways,
Do you have interceptors? My interceptors would trigger an erronious P0300 on my car. ZZP deleted it in the tune a little while later.
I have no idea how you got this code. Our cars don't have an EGR system.

Interceptors were causing me to get a false P0300 until ZZP Deleted it.
Cracked header? Maybe?? I don't see how though. You should def get that fixed!
Oh you could have some fun, Go to Autozone, let them pull the codes, and let them try to sell you an EGR valve, and then go and watch them try to look one up lol

random misfire from the P0300 code could be anything. I just replaced fuel filter after 100k and the code cleared and I have not had a misfire code yet. I'd check the simplest things like fuel filter, vacuum leaks, injectors (fuel pressure). Eliminate the small things.
