Kinda stumped, had this issue once before under similar circumstances but it "fixed itself" fairly quickly.
Went through some standing water, it wasn't deep enough for the motor to ingest it, but enough for it to cause the belt to slip for about a minute, at most, leaving the voltage hanging around 11.30. The belt dried off, voltage came back and now since then under idle or low throttle input the car runs so lean it either idles like shit (when warmed up) or dies out (when it's cold). Under any throttle input beyond (I'm guessing here) 20% it acts like normal but below that it starts to lean out per my Wideband and struggle. It seems once it's warmed up that it's back to normal but a cold start it's just a huge pain in the ass.
My tune does need work since I installed the 80's and the only new to me code I saw was about bank 1 sensor 1 O2 sensor. I reset the codes but nothing has tripped in my short time driving it besides random multiple misfire. I always had a system too lean or maybe rich which I equated to needing a retune since it only came when I added the 80's. If need be I can put the 42.5lbers back on and the tune zzp sent me home with as I never had any issues with it but the car has been running decently this way, just not ideal of course.
Is the MAF taking a shit? oxygen sensor? MAP? I just don't get how that water ok the belt situation correlates. I didn't see any vacuum leaks and all vacuum lines look fine. I haven't changed anything under hood either. Maybe the fuel pump?
