Enlighten me: how does one adjust the TPS? Can it simply be loosened and repositioned? I have nursed my Trooper along for nearly 100k miles. I bought for $175 with just over 200k and a blown head gasket. It has been a trusy steed, but some of these quirks really drive me nuts! I like the EFI, it is a lot more efficient that a carb, but sometimes it can be pain to keep tuned. I suppose it is just a learning curve. And to think I was just getting good with carberators and now I am back to square one with the EFI.

It's a race against rust and the Trooper can't go fast enough to win!
