Symptoms: Truck out of nowhere stalled on the highway during rush hour and displayed the "low oil pressure warning". *panicked.  She cranked back up just fine BUT left no CELs. I went all these years without doing the Fuse 27 mod so I thought that was it. Pulled fuse, it was melted. I figured that was my issue. wrong. Post fuse mod, truck stalled leaving driveway lmao I then started googling, saw posts saying that it may be the crankshaft position sensor and or torque convertor. First of all, that SOB sensor is in a tough spot, so I ignored that possibility for last. I then began searching for vacuum leaks and actually found some! My CAI hoses were brittle and leaking and I was missing one bolt on my MAF, leaving a gap. Still, the truck kept stalling AND the RPMS while left in neutral would fluctuate ~200 RPMS if kept steady at a certain RPM.I replaced MAF. no dice. I replaced PCV Valve. no diceThis was v hard to diag without any CELs. I gave up and towed it to a shop for professional diagnosis. The shop figured out the issue within a few days, I had 3 ignition coils arcing! I had them replace those 3 and when I brought the truck home I replaced all wires/ spark plugs.What is odd is that I replaced all coils in 2020, so about 15k miles ago with OEM parts. I'm gonna make the educated assumption that the tune shortened the living shit out of the ignition components. The truck was dyno tuned by a performance shop, so it shouldn't be a surprise that some stuff had a shorter life span. I'm just curious as to what ELSE will fail with time lol I hope this helps someone else out.</blockquote>
