90 Throttle Body butterflies- how tight should they close?
Checking for a vacuum leak before I pull the top end , I am using my custom made smoke machine, the only place I am seeing smoke from is out of the throttle body valves. I have the machine attached at the pump line +/- 5lbs of air pressure. Would this be normal leakage or are my butterflies worn?
