Ok, I just installed a CAI a week ago then after about a week my engine is making weird idle. First, when I start the car, idle is fine but when the engine gets warm, about 5-10 minutes driving, when I'm stop in neutral the engine chokes or misfires. It happen too in first gear, when moving slow speed in a higher gear. I can hear it because I can hear it from the exhaust and I can feel it too because the car moves like when you have a hicop your body do sudden move. People saying that I have too rich air, replace plugs/plug wires, idle too high, clean throttle body with carburator cleaner, and some say leave it don't do nothing. Need your ideas how to fix this. Much apprciated your help.

Thanks a lot!!

 

and you have what kind of car?

 

I got 94 H/B with mini-me B7/Z6.

 

1st thing : Reinstall original intake
to eliminate CAI as the problem.
