I have a 90 integra LS with a B18A1 engine, i bored the block .20 and the head had a 3 angle valve job. the intake was only cleaned. the car has a water usage problem and idle surges Ex: rpms go up then down up then down and so on
had a honda dealership tell me it was the intake gasket but it was new but i replaced it anyway. still cant find whats wrong. i hope someone has some advise that will help. thanx
