Replacing all 4 injectors can be very expensive. I remember there was a discussion on the list a while ago about getting injectors cleaned, balanced, and blueprinted. But I dont remember any names or tuners who do the service. New plugs dont add any HP and are a waste of money from what I gather about what other people say on the list.
Good luck, Mark Reda (I'm hammered right now, but I type really well for a guy who just downed about 15 drinks). 89 Jetta GTX 16V brd wrote: > > Well, Ron wins the prize.
