I looked everywhere I thought I could to see if I could see any holes or rot on the pipes but I couldn't find anything; I don't really hear any hissing except maybe around the (if you're facing the front of the car and looking down at the whole engine bay) rear right area, but I swear I've always heard that whenever I opened the hood, and I've owned this car for many years.
I replaced the MAF sensor and reset the code, lost one of the damn screws ( AND I CAN'T FIND THE DAMN SIZE ANYWHERE, PLEASE HELP ME).
I don't have the live data with me but as I was driving around the fuel trims still looked terrible and my gas mileage was just garbage, so I either have a leak i'm not finding or I don't know, OR it was the MAF sensor but the missing screw is throwing everything off, or maybe it's something I don't even know to look for. I am a novice DIY after all.
Can anyone help me make heads or tails of this?
