okay i decided to clean my throttle body change plugs and it was fine i drove around the block and it stalled then started a knocking noise. I messed with the intake runner flaps swirl flaps not the problem. so i finally put in a new vvt solenoid this stopped the knock but still had a missfire oncylinder 2 after swapping coils to see if it was a coil i hear a big tick and the knock comes back this is after driving it for a 2 miles and letting run for an hour or 2 to see if the knock was gone. it has no codes on my launch diagun IV accept misfire on #2. Could this be a bad pcm shorting out the vvt solenoid or ?

 

Put your old plugs back in & see what happens.
