Hey Kris, did you check the harness that goes to the computer?,(from the computer to the knock sensors are 2 harnesses) check continuity with a volt meter, also it might be the computer itself. Now, this option a lot of people will disagree with me; if the car has high mileage, check also the timing belt, including the tensioner. Good luck.

Use premium gas ONLY and if code doesn't go, disconnect the knock sensor harness and bridge the 2 sides of the wire pins with a thin flexible wire in and around the pin separator and plug it in again.
