I think it may have something to do with the power transistor, where is it located on a BB DET. Looking at a Haynes manual I see that on a DE it is on the driver's side of the valve cover (is this correct), my BB does not have one in this location. I have done some test and I am almost positive that it is ignition related.

Anyone that knows alot about these types of problems, please call me 502-296-7942 and I will call you back so I will be billed for the call.

Thanks,
Craig
