Hi guys!! I have a strange problem @ idle with my engine. AFR it's 14.7 - 15.0 and rpm 800 -1000. The problem is that the exhaust starts popping when warm..... but if turns on the lights or the A/C it almost stop doing it. Here;s a video: >http://www.youtube.com/watch?v=MKMAjtCJ-As I changed coil, leads, cap, rotor..... Thanks!
