1991 GMC Suburban 5.7 700R4 trans. New distributor, wires, coil, spark plugs, IAC, and battery. When the new distributor was install the timing was set to 0 degrees TDC with the pink unplugged. The truck is stock as far as I know but it doesn't idle correctly. I think the TPS is out of range and it looks like the IAC count to high. But here is the file from the first run with OBD1 cable hooked up to my laptop.
Any suggestion are welcome, Brian.
