Seems like you and I are in the same boat .. Just for the record, your two(2) code's (25 & 31) means that you have a lean condition (25), and 31 is the MAF sensor . Seeing that you have already changed the MAF sensor and are still getting the code, I would check and see if you have the proper signal from the ECU . If you check out my post, my mentor/friend SRK gives some excellent feedback on my issue's which have the same code's as yours . Our problem has been experienced by other's, and I am combing the post to find a solution . I will keep you posted on anything that I find .
