It's way easier and only takes about 2 minutes to jump the plug with a paper clip and get the code yourself. Then look it up, see what that code means. Just as I said above, mine was one, flashed LONG-SHORT-SHORT-SHORT-SHORT which translates to code 14 and it was the IAC valve. Turns out when I switched intakes, I forgot to torque the bolts down. Tightened em', no more problem.
