Re: Need idle help 2.9 L
Sounds like a vacuum leak for sure, the symptoms you have sure fit well. Did you reuse the TB gasket? Did you reconnect the 2 large vacuum lines and 1 small evap line that go to the bottom of the TB? Spray anywhere a vacuum leak could be, particularly around the throttle body and see if the engine idle surges. It's possible the gasket is not sealing if re-used.
