Q & ML320Truck,

I'll check all the wires and replace the ignition module for cylinder 1 since thats the hole I've had throw a check engine light.

It would be nice if it was just that simple. If it was the wire or the ignition module wouldn't I have problems at other times than just the first 1-5 min of running time?

ML320Truck, did your check engine light ever come on to clue the dealer what hole to go after?

Thanks,
Matthew
