It's worth the six or seven bucks, or you'll be grinding down a socket. And don't forget the di-electric paste when you put the new one on, or the new module will have a short life.
Thanks, Roger! Sounds like a likely culprit to me, too!! I've also read about the "tool". Looks like the TFI module comes in a wide range of prices and some suggest replacing the PIP, too. I've even seen rebuilt distributors for the price of some of these separate parts.......obviously, the idea of a "budget swap" went out the window a while back!!
