Message:
Bernd,
My check engine light flashes on and off during moderate to hard throttle. I did reset it and keeps doing it. any idea to why its doing this? Vortech supercharger on the motor. I blew the head gaskets and changed them a while back. this time I blew the intake gsasket. Now my check engine light does this. I haven't put but 25 miles on it since I reset the pcm. So any clues?

I'm not bernd but here goes:

Is it blinking on and off rapidly? Or just coming on for a little while then going off? If it's blinking like once per second your getting some major cylinder misfires.

also its always a good idea to have a vehicle dyno tested with a wideband o2 sensor after a supercharger is installed to make sure it's running alright and not too rich or too lean, etc.

yup, it blinks under excelaration. I had a feeling that is what it was. It felt like it was running kinda ruff in the low rpms. but when you get going pretty good it smooths out. I'll check my plug wire connection. Thanks.

I just checked my plug wires and I had a loose number 6 plug wire. I'll run it later on and see how everything goes.
