Update on the Chevy II.
I sent my throttle body to FiTEch they turned it around in a few days and sent it back no charge. Replaced the ECU and for some reason changed out a 6 prong plug to 2 separate plugs, a 4 and 2 prong with a larger power wire. They sent the new wiring for those plugs along with ZERO directions. Luckily after looking at it for about 10 minutes I figured out what they had done.
Good news is with the new software I reentered the motor settings, fired it up, adjusted the IAC and its ran like a champ since. I think it actually runs better than it did before. I've only put about 50 miles on it but I am considering turning the learning off on it right now.
