Argh! It's still happening. After replacing the car battery, i thought it had gone away but it started up again yesterday afternoon. Seems to not happen at all withOUT the PCA tuner module, but the fact that it did happen once the other day with NO tuner attached is confusing the hell out of me. But i am willin' to chalk that up to my dead battery.

Okay, lets assume for a sec it IS the PCA tuner module. What exactly would cause this behavior?? What malfunction or shoddy solder joint on my part would cause this to happen?
