My 2001 Park Avenue has some idle issues and I would like to remove the valve for cleaning or possible replacement. This would seem like a very basic task. Just remove the wiring connector and two tamper resistant screws. This would be the case except for the thread locking compound applied at the factory. The screws will turn about one sixteenth of a round and that is all. I have tried tightening and loosing back and forth but nothing is being gained. On a previous vehicle, I had the unfortunate experience of breaking off the screws in the throttle body doing this exact job. Over the years I have been fortunate in removing broken fasteners but these screws are very small and I had to purchase a replacement throttle body. There is not much chance of using penetrating oil to help loosen the screws in this particular case due to the lack of access. Any tips or suggestions?
