Ok, this just started happening tonight but when my car sits at idle, it idles at around 500 rpm's and sounds like it's missing and going to die. The car runs fine once i get it up past around 2000 rpm's. I do have a bad O2 sensor, and I dont know if that could be related to this problem. Dirty injectors possibly? The only mods I have done to my H22 are intake and exhaust.

Any help would be appreciated! Thanks!

 

Put in idle in search. There TONS of info on this. It could be alot of different things. Good luck
