Replaced TPS board, What a difference in performance! Options

[oakdalecurtis]

My 76 2.0 always ran pretty well, passes smog every two years. But the engine did miss sometimes at different rpm's, but usually under load more in lower gears. It has a Crane ignition, new plugs, wires, tuned fine. I finally ordered a TPS board from 914Rubber and replaced it. By the way, when I pulled the throttle body, there was no gasket or sealant present, just metal to metal! This lack of a gasket here probably gave me a small vacuum leak all along. Here's a picture of my old board. It was a little tricky drilling out the existing TPS board rivets and reinstalling the new ones. One of the rivets is under the contact fingers making it difficult to get to. With the job done, I just took the car out for a test drive. The engine started and ran flawlessly without a single miss that I could detect! It's never run like that since I got it 20 years ago. I wish I had done this repair years ago. If you're trying to fix erratic ignition missing, I would recommend replacing your TPS early in the diagnostic process and make your engine run smoothly!
