this is an old thread but I'll see if anyone is still watching it.

I was getting codes 1126 and 1133. replaced the AOS, oil filler pipe and tube. still ran like crap. replaced the MAF, immediately started running better. cleared the codes thought everything was great.
after about 100 miles CEL came on again. this time with codes 1128 and 1130.
I haven't had time to check the usual suspects yet, but I think I can eliminate the MAF. the old one was obviously bad. not only was there a noticeable difference in how the engine ran, acceleration etc... but my LTFT readings went from 35.1 down to 0 +/- 5.
I know it is possible that the new AOS is also bad. but that would not be my first suspect. I had some difficulty getting the bellow on, so it is possible I torn it. that will be the first thing I check. then I guess a smoke test to check for leaks. I know that fuel delivery can also cause these codes, but I am not seeing any performance issues and acceleration is fine. no hesitation or stumbling.

Anyone else ever seen these codes come up after replacing AOS, MAF?
