Throwing code number one cylinder misfire. New plugs and wires. It has good compression. At low idel the misfire occurs but at higher speeds is seems to even out until let off throttle and accelerate, it cuts out. Also throwing code knock sensor, believe to be from misfire.

Engine running rough or misfiring can be cause by the following. Inspect and test all the following:
1. Defective spark plug.
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
