Well, try to unplug the ecm from the pos. side of the battery. You know, the orange wire plug. They may be stored codes.
When i had a 2.0 SM in my car it was reading goofy codes like that, but it was because my chip was for a 2.1 SM.
What version of SM do you have, and what version is your chip set for?
That's why mine was giving me all my MAL codes, since it ran fine i wondered why it was giving me all them funky codes.
Yea, i just checked my old SM readings (when this was happening) and i got ALL of them codes EXSACTLY!
