87 5.0 TPI high idle at idle/cruise
The throttle sticks during cruising,and idling.(off and on) If i tap the gas pedal it comes down..Any clues?? I've changed the TB gasket,the intake runner gaskets,cleaned out the TB as best as i could,egr gasket,and checked for vaccum leaks....Still didn't help..
Thanks
