Hello, 1997 TJ and need help diagnosing this issue, was driving Jeep home from work and out of no where it started to rock some while driving and the engine sounded like it was going to give out. Took it home and replaced the spark plugs and wires. Still is having issues with rpm and and rough driving, the engine as well doesn’t sound too good. Any ideas or pointers of where to start? Thanks, video is @
