I had a misfire before but it’s not showing any codes anymore after I had someone chase the thread on a spark plug cylinder that had a stripped thread. It also has rough idle and alotta hesitation while accelerating. I’m not sure what cylinder is giving me an issue as I had a helicoil installed on the other cylinder

Are you sure it isn't a bad accessory or exhaust leak

#

Pull plug wires

#

If pulling one makes the engine not change in how it's running that is the one misfiring

# oak nacelle Did you tighten the sparkplugs

well lol I did a lotta stupid things including not using a torque wrench I tightened it up until it was tight and wouldnt budge, but there are no issues or sounds coming from those cylinders tho
