VSS can cause a soft misfire they claim, it effects the PCM.
seriously? Anyone but you i would tell to pound sand. First i ever heard of such things. I'll look at the FSM in a bit.
The longer i work on these things nothing surprises me anymore.
So it sees 0 Mph and other signals say 3000 RPM and x TPS and y airflow = scrambled eggs.
I did a 2000 Chevy van that was breaking up like crazy at 3200 RPM, bad VSS.
