Could bad O2 sensors cause a car to act wierd and stall???
After a few days without problems, I started today after work and it was possessed. The car idled between 200-800 - up and down as if someone were playing with the throttle (DBW always make me worry). When the car was in gear and moved it was fine. FInally after a few miles of stop and go - I finally came to a full stop and it died.
I quicky tried to restart - it started and the idle was steady - no problems. Ok - so I continue how and it starts again about 1/2 hour later. Finally, a few miles before home - the CEL comes and stays.
Hook up the VAG and - Fault codes shown are:

Is this simply the O2 sensors? Seems pretty spooky for just an O2 sensor - but i guess you never know.

I just replaced my maf plug. Looks like a dead maf to vag-com and....
responds well to being unplugged. It was definatly a dirty german trick.

Riebes Auto Parts in Loomis, CA can suck it. Thanks for the help bitches.
IIRC, unplugging the O2 sensors would cause it to run in open loop, so it wouldn't
necessarily be better, but it would actually run. If the ECU got weird signals from the O2 sensors, I would think it'd just go nuts itself.
How many miles on the car? Might be time for new O2's.
Oh, clear the DTCs and run them again.
