I am in need of some experienced advice here. I bought a 1994 gmc 1500 with a 5.7l from a 1995 Tahoe, and a 700r4 transmission from I don't know where. The truck runs and drives, but runs extremely rich, and runs codes for a variety of different sensors including the maf sensor, mat sensor, 02 sensor, and IAC. The IAC is wired incorrectly because the after market harness was all black, and the wires were not put in their correct places. The truck has a custom 2.5 inch exhaust with no cats. It runs like **** on start up, and wants to bog down. If anyone can give me some advice I would appreciate it
