hi all, ive a 94 import with the 3sge engine, ive just fitted a apexi induction kit and a apexi exhaust and car idles lumpy, ive read that i can reset ecu to combat this idle issue by taking out hazard fues , ecu fuse and efi fuse, wait a minute then put them back in and let car idle for 10 minutes then switch off the on again and car should idle better, but min doesnt, it sounds the same, i found hazard and efi fuse ok but theres two ecu fueses, one in engine bay and another in the car by drivers lower dash, do i pull both these out or have i missed something, cheers rob
