Please help Mods done now CEL P0171, Logs provided

[joejoe555]

I only have limited understanding of how to log and what to look for. I have a couple of files and willing to test log and post any more for some help.

I put on an intake with stock maf sensor and bov I also bought a tactrix cable to read and right now have limited knowledge of how to use ecuexplorer and engunity the 2 softwares i am using to log

my cel is lean on bank 1, so i am guess air/fuel on sensor 1 was what i should look for this is what i saved.

Sorry for being a noobie i am trying to read as much as i can but i could use some help

If you are having problems after doing your mods be sure to look for air leaks after the Maf sensor. Also make sure all connectors are plugged in securely and that your Maf is installed in the correct direction. Many people have installed the Maf backwards which will cause a number of driveability problems.

no leaks I checked pretty thorough. I heard its possible my maf is to far behind a bend on crappier intakes which causes problems. It isnt the best intake but i dont see why it would have a problem. MAF has to be in right cause i could only put it in one way.

I will put some pictures up. Please post more ideas on how to level air/fuel mixtures so i am not running lean and what i should log
