Hey dude,
For some reason, the last time I assembled my engine and cranked it for the first time it threw those two codes too. Dunno why - shut everything down, they tested okay, reset the computer, and I've never heard a peep out of those codes since! Try resetting the computer first to see if the codes reappear. If they do, I can post how to test them. <img src="/forums/images/graemlins/wink.gif" alt="" />
