5.3 evap and intake question
The other question I have is that I have about a 1 inch diameter hole on the top of the intake about 4 inches back from the throttle body and near the EVAP solenoid. It looks like something used to be there and was broken off or pulled out. Does something go in this or is it supposed to have a plug of some kind like some of the other ports in the intake. If it supposed to be plugged does anyone know the part number or have a good suggestion on the best way to plug it.
