P1133, P1126 Woes
Hi Guys,
So ive cleaned out my MAF car drove great and removed many codes i had before but CEL soon popped up again. Today I took the car to Checkers and these guys showed up:
P1133- Oxygen sensing adaptation, lower load range, bank 2
P1126- Oxygen sensing adaptation, lower load range, bank 1
The codes were present before i cleaned the MAF so i must not have fixed what was wrong.
Their tool was unable to run the FT levels and 02 levels so im left with your guy's expert opinions.
I did notice when the CEL came on I was in 2nd gear and nearing 4k rpm foot to the floor the car jerked almost like it was missing or getting too much air or fuel or something and then the light came on.
Seems to replicate everytime im in 2nd but not in any of the other gears. Coincidence?
All caps are tight, I have not seen any vacum leaks or liquid leaks. Car idles correctly and changes when i remove the oil cap so i think its pretty tight. Any ideas, opinions?
BTW does the dealer ever charge to read your codes?
Car is '01 C4 with 116k mi
Thank you for any advise

My 2 cents is that after replacing 2 (out of 4) O2 sensors for this issue to no avail, I learned on this forum to try cleaning the MAF with $4.99 electronics cleaner. After the first cleaning the CEL didn't show up for about 2 months. Cleaned it again, and it stayed off for another few months. And so it goes. I have a Schnell cold air intake and filter and have come to understand that after some use the MAF may get fouled. This regular cleaning solves my problem.
