Full Version: Throttle body pressure test?
Hand over throttle body while running should stall it ? (Pressure tested?) lol. If it doesn’t stall out than there’s a vaccum leak somewhere?Correct?
Would thing so, but maybe the AAR valve is stuck in the open position.
Aux air R I’ll find it and check it! Thanks

It’s only different in the engine bay location of the charcoal canister. Otherwise the same.
