chugs,cuts-out only after 10min or so Ok i pulled my plugs yesterday to regap them and ,only on the driver side , the plugs were dark as hell like it had been running rich.?!? i noticed the bung i had welded onto the pipe was so tall that only the very tip top of the sensor woas sticking threw the bung so i grinded the bung down,oh yeah (this was an aftermarket bung that was different than the other side),and the sensor was sticking into the pipe like it should .So i figured that where my cutting out and chugging was coming from.Well today it did the same exact thing. and this isnt revved up or seeing anykind of boost, this is normal driving maybe qtr throttle on the highway to work.It has been doing this for a while now and i am getting frustrated with it. Does this sound like a bad O2?Almost seems like it is going into closed loop and doing this,cuz it will run great then after being on the highway it goes to ****! I thought the O2's usually heat up pretty quickly and goes into closed loop.I would think this would happen rather quickly.

i am running blow thru and on my way home after work today i unplugged the driver side o2 sensor to see if it was the culprit with horrible luck...it actually was worst and died on the highway. i plugged it back in and it ran better but just as bad as it did to start with. would a bad maf do this?

well yeah.....but like i stated before , i am not hitting any kinda boost going back and forth to work..but so far havent had the time to datalog it yet. i am thinking my maf might be the problem, but i dont get why only that one sides plugs were the only ones looking odd.

Also, did you descreen it? Descreening it just makes it more dumb since it removes the straightness of how the air flows through the sensor.
