So every post I see about this code is also paired with p0174, I’m only getting p0171 so I don’t know if that narrows down the problem. Car seems like it is struggling to breath just a little bit. My mods are below and just 2 things to note, I changed my tensioner and tensioner pulley and I left the intake off the night before just so it would be easier to put on the tensioner the next day, the intake was left under the hood, just disconnected. And the other thing is that my neighbor told me she saw someone that looked to be taking pictures of under my car, I don’t see anything that looks off under the car, I’m assuming they were looking to steal cats

Edit: now I’m getting p0174 after cleaning the intake filter

P0171 came in as vacuum leak when I googled it. P0174 came in as lean condition. It would point to a missing vacuum hose or the intake not fully seated. Probably you knocked something loose when installing the intake or the intake itself is not seated tight.

Hmm I read that it meant bank 1 too lean, and can also be a leak, I guess one could cause the other. I’ll definitely start off with checking the tubes connected to the intake though
