Yo, I need some assistance. I've had LTs and ORY since June, then the car was tuned in July, o2 simms were deleted etc., No problems, then bam, last night I get this P1133 Fuel Air Metering doodoo code. What is this crap. There are no leaks or anything. I'm having my Magnaflow catback installed Wednesday, should I have them switch the O2 sensors from the passenger's side to the driver's side and see what happens? Any help would be great.
Thanks,
Tony

That's not what the code means. It means "Insufficient Switching, Bank 1, Sensor 1". Make sure your O2 didn't wiggle loose on Bank 1 for starters. And check the plug/wiring for damage. You may need a new one.

What about the 02 extensions?

A lot of us have this code after LT's. Sometimes you can replace the O2 but this does not always correct the problem. See thread for some other people having the same code:

I read another thread that said replacing the O2 with a rear vet one did not fix the problem. I took mine out and cleaned the O2 and that helped for a couple of months before it came back. Right now I have a new O2 on that side right now. I am not sure how long this one will last.
Good luck.
