Question about Chevrolet G20
I would recommend that you check for vacuum leaks..from experience i can tell you that i have changed hundreds of throttle base gaskets. check out with a propane torch at base of throttle body as soon as you hit the leak with the propane you will notice a stumble in engine or an increase in idle speed.. i hope that helps...let me know
