Truck is throwing that damn P0101 code!! (SOLVED)

I went to take my truck fishing Thursday on the way there I noticed it wasn't running right. I was watching my AFR gauge and when it would stumble the AFR would go way lean into the 16-18 range. I got it back home pulled codes and had the following P0101,P0102,P0113,P0171 & P0174. I pulled the MAF sensor and cleaned it with MAF cleaner reinstalled and cleared codes. I took it out the next day and same thing could feel the truck stumble/hesitate and the AFR was still going lean. So I put the scan tool back on and now only have the P0101 (pending) code. I swapped out the MAF sensor and still same thing. I have checked for vacuum leaks but I don't see/hear any and my boost/vacuum gauge is reading 20in/hg. I have a AFE Stg.2 Si (sealed intake) which I have had since 2011 and before that I had the crappy K&N CAI with no issues. I did a little research on here and only fix I found was to switch back to OEM air intake and it stopped throwing the P0101 code and another switched from TRD 2nd gen CAI to a 1st gen and it fixed it. Does anyone have any other suggestions?

 

you swap with a new sensor or used?
id start with a new oem maf and see if that helps
unless theres fuzz or something on the wires that would cause those codes also

 

It was a brand new OEM Denso MAF.

 

Have you checked the wires and connector at the MAF sensor? a broken wire or bad connection can also set the same codes.

 

Okay I'm back at this again, I have checked the wiring at the MAF sensor and connector itself it all looks good. I checked my catch can fittings for a leak. I disconnected the battery for 2hrs yesterday then took it for a 15-20min drive. Hasn't changed a thing so far. Today I noticed while setting in the driveway with it running if I bring the RPM up slowly to 1700 it starts running lean about 16:1. Then as I slowly increase RPMs before I even get to 2,000 RPMs it goes dead lean and pegs my AFR gauge at 18:1.

 

Have you checked fuel pressure? Going lean is a hint in that direction.

 

I have not checked fuel pressure yet. Thanks I will try and get it checked when I return home in a few wks.

 

I swapped out my Pro Guard 7 for a Pro Dry S yesterday, as well as wiping out the intake tube and giving the MAF sensor a good cleaning with some CRC MAF sensor cleaner. After putting it all back together I took it out for a 60 mile round trip and even drove it this morning to the feed store. I'm happy to report that all the issues are now gone. The truck feels so much better power wise. I would like to thank you all for your help I really appreciate it!
