I might add that after I replaced the intake gasket, the idle was still not right. I changed the throttle position sensor and all was good again. Spraying the intake gasket with carb cleaner did not affect the idle either. Even so all the car guru forums said the gasket was leaking according to the symptoms. Apparently the OEM gasket is a rubber coated plastic gasket. The plastic cracks and then the rubber leaks. Was replaced with a FelPro brand intake gasket.The TPS literally fell to pieces when removed.
