you do know that the error code is stored in the ecm untill it is cleared, right? To clear it, you need to pull the ECM fuse for about 20 secs, or disconnect the batt. Also, I think that every 50 starts clears the ECM. Good Luck.

i replased th mas sensor and cleared the code but it the eng light keeps coming up and the same code :naughty:
