I got my car back from putting on a few mods(midpipe,1300cc injectors,greddy pullies,ACV block off) and the car was working fine. Going to the dyno to get it tuned this month. been easy on it.I might have put a total of 150 miles on the car since getting it back.
Well i was driving over to a friend's, the car was still warming up, I pushed in the clutch to slow down to take a right turn when the idle jumped to 2000rpm and started surging to 2700-3000 rpm. I pulled over into the shopping plaza right there and checked for obvious vacuum lines that might have popped off. i couldnt find any. Drove the car back home, reset the ecu twice. nothing. the car still fluctuated at idle. I did a search and found idle surging problems but nowhere near 2000-3000 rpm surges. please someone help me. what should I look for? Thanks
