Hey. I have been racking my brain to figure out why my car runs like crap. When its cold it will start right away then die. I have to keep it revved up for a few minutes before it will stay running on it own. Before it starts running smoothly it will rev up to about 1800 then down to 500 a few times and level out at 1k-1200. I have already replaced my IAC, cleaned the throttle body, checked plugs, wires, and rotor. O2 is new. I also changed my injectors and the same thing happens. I hope to hell its not my cal. Can somebody please chime in and help me figure this out.
