Anyone run into any problems with using an auto t-body and intake? The auto IAC valve has three wires and mounts on the t-body. Two of the wires go to the ECU in pins A13 & A14. IAC + and IAC-. On a manual set up, there is only two wires and it mounts to the intake. Tried fooling the ECU and it surges at idle REAL bad. The guy is trying to run a 97 auto upper end with a 98 bottom end and 97 5-speed ECU. I think the only way to fix it is a 97 intake assy.

Any ideas?
