hey guys, im new to the forum and i m having a problem. i just bought a 99 mustang gt from a shop. there is no way i can find out what the previous owner has done to it. the other day i was driving in 4 gear and noticed i lost power. the car shut off on me and i had to wait to restart the car. it seems like its fine now but its the second time it has happened to me. bought a obdII scanner and the only error code is p0113(intake air temperature circuit high input). what does that mean and how do i correct the problem. i've already had a tune up done...
