front 02 sensor is going out
i'll betcha.....


if you can check it with your scanner
see the amount of correction going on in the AF mixture
car is trying hard to keep within specs

based on my experiences
I'd have to go with a soon to be dead fron 02 Sensor...

same deal happened to me not too long ago.

I know this may be completely unrelated (as I own a VW), but every little bit helps.

I made a U-Turn, and all of a sudden my idle started to dip from ~600 - ~2000 RPMs and back again continuously. Sometimes the car would stall on some of the dips. So driving the thing around was a bish . . . especially slow rolling starts.

I had my Passat in the shop for almost 2 months while the asshats didn't know all that was wrong was a fuggin' burnt FUSE!

I got 16 engine codes from this one fuse.

Any mods to the car? Throttle body coolant bypass?
