I was riding along in some heavy rain when trying to jump onto the highway, suddenly the truck loses power for a bit and throws a CEL. I'm running a custom tune on a Cobb AP BTW, so I use the AP to tell me the code and its a P0301. I pull over and let the truck rest for approx 2 minutes and the CEL goes away and I finish out the rest of my road trip. Once I get to where I'm going I give it another WOT run and the CEL comes back with the same code. I pull the plugs and coils and find nothing wrong with them visually whatsoever. I use the AP to clear the code and reset PCM learning and make it back home (approx 240 miles). Once I get home I take any and every ignition related sensor off the and clean it to include removing the throttle body and cleaning it as well. I cant find anything that would lead to believe their is a hardware failure anywhere on the ignition side of things. to my surprise everything was pretty clean for a truck that has 58k on it.
Has anyone else had any issues like these? I have done some preliminary research and saw that there is a misfire monitor reset procedure that FORD can do but am wondering if there is anything else I can check before taking it in as there has been no major maintenance done to it at all.
Truck has stock CAI, SPD SP542 plugs gaped at .028, and Cobb AP Custom E-50 Goosetune.
My concern now is that while monitoring the misfire count per cylinder it gets random misfires throughout the cylinders even on my 20 min commute to work. I don't necessarily feel any loss in performance but also don't want to let this keep going if it is indicative of a failure soon to come. It has not thrown any more codes since then, I fully reset learning again after I installed everything after the thorough cleaning. Any suggestions would be greatly appreciated, I travel often and don't wont to have a constant worry in my mind about issues down the road as it will drastically reduce the joy of driving it anywhere further than my typical commute to work.
