Well, after changing my fuel injectors, O2 sensor, TPS, ECT, Distributor, and DIS Module, the car acted WORSE THAN EVER on the road. So I came home and unplugged the knock sensor on a hunch. It cleared right up. Keeping in mind that I have an N/A, does this mean the sensor is bad? Or does it mean something much worse? The only thing I can think that might 'sound' like a knock to it is a valve that clicks a little bit. I think this knock sensor thing was causing alot of my problems. I've gotten the air/fuel mixture leaned up a great deal. So, where do I go from here? I have another sensor in the yard, and chance it's any better?
