    These codes are from Auto Zone free scan. Also I posted this thread in the general help section on this site by mistake.

    flashing SES = current misfires.

    113 = IAT sensor high voltage (bad IAT or pinched/shorted harness)
    0107 = ECT low voltage (fix this!!)
    0300 = random misfires

    Car ran great for short period. Idle for 30 minutes or so warming up. Sounded great. Filled with coolent and all other fluids then drove it. it developed a misss. Mabey a bad ground?
    There is one wire Im not sure of. Its located on the driver side, in the same loom as the alternator wires, temp coolent, and O2 sensor. It is the longest wire in that loom on a 2000 TransAm. It is a ground and Im not sure I put it in the correct place.
