I recently purchased a turning chip for my '91 F250 with a 5.8L off ebay. It says to plug it into the connector on the IAT sensor, I plugged it into what I think is the IAT sensor connector. I cant even push the gas pedal all the way down now. The truck also idles really low. I was wondering if anybody knows where the IAT sensor is on the truck.

Thanks,

I believe it is in the lower intake in one of the intake runners, but I'm not 100% sure. btw anything you plug into the iat to get more power isn't going to help much, only fool the computer into adding more fuel and timing, which can be bad somtimes

 

I really would not recommend this type of modification as it will do nothing but cause more problems than it's worth, and may lower your fuel mileage.
