Wrangler misfire?

[Steven5000]

George is at least 1000 times smarter than me (but I did once, decades ago, work in a shop). The mechanic that changed the ignition parts had a good look at #2 spark plug which should have showed something if there is that bad of a problem with the Heli Coil. There was probably some malfunction at all speeds so the speed you were driving may be somewhat coincidental unless you were rapidly accelerating. If you think it’s an otherwise good engine, I like the crank sensor (or something else electrical) which should throw a code but you never know.
