Do you have the correct PCV valve installed? Also have you tried scanning for codes? I would use a more advance scanner for that rather then the quick small ones.

I have ordered the PCV valve. The only code that shows up is a knock sensor.

Okay, replace the valve and reset the light and let us know if that fixed the problem or if the code returns.

replaced the valve, the only code is a knock sensor, an if still backfired.

If your engine has one it will be near the exhaust manifold on either side.
