Well the harmonic ballancer has teeth so to speak that passes basicly through a magnet wich would be called the crank position sensor. I cant tell anything about what is going on when you say the timing falls off without a scan. So send me a .hpl file if you happen to save it. I have hpt so I will be able to read it...matter o fact post a scan depo scan so everyone can see it.



I could be wrong but i don't think that is your problem...any dtc's
