Not trying to kick a dead horse but, P0171 /1135
I have searched all over and it appears that there is no real consensus on the a definitive answer (here recently anyhow) on what the most common culprit would be for this combo,
The engine light is intermitent. Gas mileage is roughly 18-19mpg (AWD). Idle is rough but steady @ 1000rpm. I am thinking the rough vibration is caused by failing motor or tranny mount. Only issue I have with rpms it at 70-80mph and running 3000rpms . Yikes if ya ask me. I have athread about that and getting help but could a bad connection on the MAF cause such high rpms at higher speeds or the combination of the codes for that matter?
Happy Thanksgiving guys and I appriciate your help.

LOL Hyper, You told me a while back that it was high. Not trying to call you out at all bro. As for the codes, I am going to clean MAF again, Clean the contacts and go from there.

You said 4k rpms at 75mph... So obviously I would say that's high. Because 4k is high!
LOLIn the post after your's I explain that I get 3200-3400 rpms at 80.

Find the post. I'm pretty sure I didn't. I run 3200 rpm at 80mph.

Lots of crap running thru my mind. I have enough check engine lights between my two vehicles that I could probably make a christmas display. Once again. I apologize.

Hahah. No worries!
For the P1135 you need to replace the Bank 1 Sensor 1 (this is behind the engine block). I would ignore the P0171 because it usually pops up with the A/F sensor.

Yes sir. FYI autoparts123.com are having a 20% off special. If you are a first time user I believe it is also an additional 10% off. I know they carry OEM parts. They are just hit and miss. I am not affiliated with them. just thought I would share the love.
Once again Hyper, You're the chit and I am a total Jack@ss

Hhaah, don't worry about it, it's all good!
Just make sure it's a Denso sensor.
I'll check out the website, I do need a new air filter and a cabin air filter. So might as well buy from there.
BTW: Happy Thanksgiving!

P0101, I'd take another look at the the MAF and make sure the diode and the inner wires are entirely clean. That's not a common code. Also look for any kind of leak beneath the MAF (o-ring). The MAF itself could be bad despite cleaning (it's happened to me before).
The other 2 codes are likely related to the P0101 occurring, because if it can't meter the air right...then the air/fuel ratio is off.
