Knocking?
Do you get DIC codes when the engine senses knocking? My car either has loud valve noise or knocking when the car is bogged down in 4th TC locked (Giving the car light throttle at lower speeds, not enough for a down shift). I have had the car dyno tuned by NLP after a LGM headers installation. I've heard that valve noise is increased with headers....
How can you tell the difference between valve noise and knocks?

Best way to test it, put 4 gallons of 104 and fill the tank. If it was bad gas it will go away, if not have some tuning done.
