Codes that came up are as follows:
P1128 17536 Bank 1 Too Lean
P1137 17545 Bank 1 Too Rich

I replaced both 02 sensors about a month ago and that *should have solved my problem, but it didn't. I cleared the code after replacing the sensors, and now it's back. I was told it may be a faulty MAF. So disconnecting my current MAF to test and see if it's bad probably won't do anything because it isn't causing that much of a decrease in noticeable performance. How else can I go about fixing this problem???

Also, where is a good place to get a new MAF if I need it...I believe my engine code is ATW....
Thanks.

Hey neighbor,
Sounds like you need a MAF sensor.
I think I have a new one stashed somewhere......If you give me the part number Ill check and see if thats the one you need.

 

Try cleaning your MAF first.

 

Who cleans a Maf?

 

Uh - people who aren't idiots...
