I once saw a mechanic sprayed lubricant then knock the side of the body the screw is mounted on, gently. I guess it is to slightly dislodge the grip of the screw. Not so sure. Might work though?on recent long weekend, i was tempted to clean my throttle body.
while dismantling the whole thing, suddenly i faced a stuck up.
i didnt manage to take out the screw holding the IACV.furthermore i ruin the head thread (bunga) of the screw when using brutal force.
but i just went on to spray/clean the throttle body without cleaning that IACV sensor.
anyone have an idea on how to take out a bad screw??
