Hows it goin everyone? I have a 89 Fox GT 5.0, offroad H pipe, mufflers, a BBK CAI, 95 GT MAF, and a 70mm Throttle body. The issues I was having were hesitiation, backfiring, and wouldnt idle. I replaced the TPS with an autozone one, they told me they needed my OEM# off mine but it already had a replacement in it so I had no # to go by and I bought the one they stocked along with a new MAF for a 95 GT. Installed the parts and adjusted the volts on the TPS and everything ran perfect. No more rich oily gas burning smell or missing and perfect idle. Now every once in a while when I shut the car off after running great or sitting all night my check engine light is on and it wont idle and is dumping fuel. Any HELP?

PS: I have only checked my codes once so far, but how do I clear them to start over?
