The TL;DR of all that for me was that the MAF needed replacement, but the post walks through a bunch of troubleshooting steps, and shows how to work with a bunch of the system that generates the P0171.

 

Yes it sure did help the trims. I’ll grab some numbers this week. The tach is an odd issue that I have no idea how to fix lol
