Has anybody had any luck with remainufactured parts on their trucks? I put a remain distributor on my 1990 GMC Seirra 5.7L and the darn thing will not stay timed. It is bouncing about 4 degrees off, 2 degrees either way. It doesn't seem to be effecting general performance to bad but I just wonder what the truck could do with precision timing. Just wondering if anyone has had the same problem?
