1997 t100 3.4 are there any wiring issues common for the maf and/or iat

Not sure of wiring problems per say, but I do know if you have higher mileage like 125,000 +, they seem to have a problem with the valves tightening on their own, and the MAF seems to give problems. Have your valves adjusted, and your MAF tested.

seek a diag from a good tech b4 starting to guess at whats wrong
