I had misfires quite a bit asociated with maxed out trims, fuel pressure diving exspeacialy when I went to RB's. Installed new O2's and codes went away. After that I installed the cobb AP with BMS backend flash wich really smoothed out things. But the culprit for my fuel mixture codes where the O2's (primary).

30 min job tops! rememer to not twist the wires when installing them.
1. Remove engine cover 2. remove/unplug both connectors (black wired O2 goes to front Dp, Grey goes to rear Dp) 3.free both wires from clips around valve cover 4. take belly pan off 5. undo both sterring rack bolts and move seering rack out of the way 6. remove 02 sensors and reverse steps.

I replaced my primaries and this didnt fix the problem, but it did get rid of the lambda sensor codes.

Well they did a couple of things. They cleaned the intake valves (walnut blasting), and replaced a seal on the turbo pipe. Neither one corrected the problem. They finally replaced all six injectors. That is what I'm testing now. Thus far the code has not come back. need to drive more to be certain.

Ok, cool. Hopefully it was the injectors.

Hey guys,
Car has been giving me the 2A2C code for a few weeks now, but it goes away after a few minutes of driving and car suddently goes to normal, leading me to believe it is electrical. At start, it studders like crazy, doesnt want to move, slow acceleration, etc. Then, as stated above, it like flips a switch, SES goes away, and its fine. Happens on almost every start up! Any idea what could cause this and resolution? Really annoying, and want to get my car all nice and running.. cant let these things pile up on me lol Thanks! |
