Hey all, I'm curious about the misfire code cycle. Logic (at least mine) dictates if something misfires once, it should constantly misfire until whatever caused it is fixed. I threw a Cyl 5 misfire. Cleared it. Ran about 100 miles. It popped again. Changed the plug. It popped again. Plug is fine, Fuel Trims are still at 0%.
Ran it another 200 miles, never popped. It was pretty random.
Can these codes be stored a long time and then just re-appear? My only guess is that the coil for that cyl is going bad, but it didn't pop on the opposite cylinder.
Plugs were all pretty new, wires are 8mm and new. I had done a lot of work resealing the valve covers and intake and whatnot prior to this.
To my simplistic understanding if there's something causing a misfire, the misfire should be constant. But this wasn't. Very random. Similar driving type and temperature and all that other stuff.
