vq40 timing chains
doubt that you skipped any teeth on the timing chains. Once you open it up, you will see how it is set up.
Recommend that before you start taking it apart, make sure that your P0300 problem has been corrected and not being masked by a crank angle or camshaft sensor failure. I had two of the three sensors fail at different times that caused hard starting, stalling, and of course, lack of power.
hope this helps
