high idle..what else besides throttle body gasket
I started by 89 suburban (350) after is sat for a week and it is idling very high probably 2500+rpm (don't have a tach). Never has this before
popping the gas doesn't bring it down. A vacuum leak would make it idle rough, not high, right?
I haven't had time to check much, but any other things I should check besides vacuum leaks?
Any ideas would be great thanks.
