Update.

Marc is the Bomb! Thanks Marc.

I had an issue with the cooling fans staying on all of the time and the full power stopped working after about 4 minutes with Marc's updated PROM in.

Marc said to look at the PROM and make sure that it was completely seated in the port. I took off the cover and looked carefully at the clips on the side of the prom and I had to gently pull up on them so they fully snapped in the up position. After I started to put the ECM back together, I noticed that the green connector going into the ECM was not seated in all of the way. I pushed it back in and I felt it click into place. Now it has full power and the fans kick on at 98 Celsius and shut down at 89 Celsius.

Marc's update to the prom is a noticeable difference. No back fires so far and it pulls like a freight train.
