I'm running the Siemans 72# injectors with the Acceleronics Box and just flunked my Smog Pre-test in Ca. All you running Low Z injectors have any problems passing smog due to the big injectors? Or should I say any of you with the big injectors think they are causing you to run rich at idle. My car is running real fat at idle and a little fat in the 2500 rpm test. i'm also not getting the EGR to work at all which may be cam related but I doubt it cause I've passed before with similar cam. I'll be checking for vacuum leaks tommorrow. Any thoughts would be appreciated.
