Hello, I'm new to this site and was wondering if anyone could help me. I have a 95 F150 4x4 with a 5.8 in which the previous owner installed a hypertech chip in it. I've been having problems with the truck cutting out and running rough at low rpm's so I put a tune up on it plugs, wires, cap, rotor, and coil and that didn't fix it so i took it to the local shop and he told me his computer couldn't read the trucks. He said it was because of the chip. So how do i reset the computer so he could read the codes. Any info would be greatly appreciated.
