My GLI 16V CIS-E is running sluggish, and won't rev over 4500. I suspect the tappet noise and maybe other noises are making the knock sensor back down the timing and whatever else it does to stop pinging. So how can I check this? What happens if I just disconnect the knock sensor
- will it revert to "normal" uncontrolled parameters, or will it go full scale one way or the other? Texas Parts Guy
