hey there i have a 1994 vr 5L with an idling problem. its got a sort of a miss but dont brake down when i rev it. when im driving it shunts at low revs when im going 60 km at about 1500 rpm and at 100 km at about 1800 rpm. iv replaced spark plugs leads fuel pessure reg most vack hoses (map sensore etc..) iv had it on a scan tool no codes only sus thing is that at idle the oxygen sensore reads rich all the time and then when i bring the revs up it starts working fine (rich lean rich lean etc..). not much mods just a 192 kw chip that bumped my rev limit up 1000 more revs it was tested befor i used it and worked good. iv had carby cleaner out looking for vac leeks but found none. its been realy buging me so if neone can help would be great thanx
