Okay, I have a few things to check next time I have time to work on the car. As part of it, I will do the exact test Barry12345 suggested. I really want to nail things down too. Unfortunately, although I have tried to be methodical, my lack of knowledge has limited me. As far as I can tell, I have isolated the issue to some extent. Although I believe I already have done something very close to the test Barry12345 suggested, I will do that EXACT test.

Unfortunately, I will be away for a while, but when I get back, I will get back into things. As always, any ideas and information are always welcome. The more I know about IPs and jammed racks, the better I will feel.
