hey Scotty i've just rebuilt my eclipse engine, but I've noticed a knock , when the maf sensor is plugged in the tps become non responsive (if you move it the engine won't idle low or high) and I rev the car I can hear the knock ( like a rod knock), if I unplugged the maf and rev it the engine sounds nice and quite. One more thing the knock sensor is broken, could that be the problem? or a bad tps?
