BF,
Disconnect power to the ECM, either by removing the ECM power fuse or disconnecting the battery. Waint ten minutes and reconnect. Test the ECM for codes before you crank the engine.
Waiting for results...

Well Vader it will still not thow a code. I will still not Idle (unless I crank the idle screw out) and at Idle I am getting 12* advance on the timing with the base correctly set at 6* ( set the base with the wire pulled it just jumps up itself on the computer)
Thanks
Brian
