Electrical problem
1999 Buick Lesabre 6 cyl Front Wheel Drive Automatic 57,000 miles

I purchased a performance chip from SLR Motorsports to increase the horsepower, but mostly to gain gas mileage.

I need to know where the IAT sensor is unless it is integrated into the MAF sensor then I need to know where that is located

They are two different sensors. The Mass Air Flow sensor is located in the air cleaner duct between the engine and air cleaner housing. Do not confuse it with the Intake air temperature sensor. The IAT will have 2 wires. The MAF will have maybe 4 or 5.
