Missing 360

My 2001 Dodge Ram develops a miss, mild to severe after it is warmed up; driven 25 to 30 miles. this miss is intermittent. I might last for 2 miles or 10 miles. Dealer thinks it could be a coil acting up. I need help so I can have it ready for the snow season.

replace the coil. It shouldn’t cost too much & worth a try.
