I have gotten some help on here before, so I am reaching out again. I have a 2012 GT that has an "intermittent" misfire (meaning that when it really acts up and triggers the engine light) when passing at highway speeds. Just sounds like the exhaust is off all the time too.

Anyway, I'm lost what to do next to try to fix it. I had the transmission replaced, so I had the dealer recalibrate it, replaced the crankshaft sensor, replaced the camshaft sensor, replaced plug, alternated coils...
