Well i have a 92 lude with a h22a V engine swap. I belive it was from a 95 lude.
Heres the problem. When i use the headlights at night, when my car is at idle it revs up and down kinda like its breathing, but not when there off. Its real anoying since my exahst is loud as sin. ANy ideas would be awsome, lord knows ive tried alot.
thanx
