I am another victim of the 1124 and 1126 codes. After much research, I think I have a handle on it, thanks largely to threads like this. I have learned not accept any post as the gospel, since many posts on the net say these codes are because the engine is running too lean, and others say it is too rich! My thanks to insite, he has it correct. My longterm trims were -21.1% and -21.9%, with a MAF reading of between 5 and 6 g/s at idle. After removing and cleaning the MAF (dead easy, 15-20 minutes from start to finish) the MAF now reads 3 g/s (2.98-3.19) at idle, with the longterm trims after a week of driving, at -4.7% and -6.3%. So as I read it, the MAF was reading too high, thinking there was more airflow than there really was, and was scheduling additional fuel to support it. The O2 sensors were then trying to trim back the rich mixture to something more useable, causing those high negative long term fuel trims. So far so good on the CEL light, if anything changes I'll post it. Thanks guys, Rob
