what is your vacuum reading at idle inHG? If you have a vag-com look at your block 032 at idle and post the readings...to tell if the maf is bad, either do a wot run, in 2nd would be find and log your air mass in g/s...you can also tell by unplugging the maf, if the car still feels the same way when it is plugged in, = bad maf....could you list the codes that were cleared after you replaced the o2 sensor...your possibles are vac leak, maf, fuel filter... seems like from what you said, its a bad maf... how many miles on the car and what mods?

RE: Code P1128...help
were the 3 codes.... P1128 was the only one that came back on after i cleared them.
65,000 miles .. no mods...
basically this is exactly what is going on....
when i start up the car the idol flutters up and down for about 8-10 seconds maybe 800 rpms. It then levels out…. It also sometimes does it when I come to a stop after driving. When I put gas in my car no matter if its 3 gallons to a full tank I have to pump the gas petal while cranking the ignition to get it started. Not sure whats up with that. Another fantastic thing that is going on is sometimes when I go around a corner or just simply going straight .. when the transmission miss-shifts…. Sometimes goes into neutral and revs…. Sometimes when I come to a stop it actually puts the car in reverse…. When I use the auto-stick (whatever its called) and manually use the paddles on the wheel to shift it doesn’t really seem to do it. Maybe its doing that because when I had the oil changed the idiots drained the transmission fluid instead… then had to put their crappy fluid in… because If I remember correctly that started around that time… but then again who knows. So those are the problems that are going on… .ugh

Your car is posessed. Sell it asap. Strange stuff. I still think your MAF could be bad. It might be a vac leak though, I wouldnt rule it out. As far as the tranny goes, you better figure that one out asap.
