Had an issue come up on my 2019 1500 yesterday. It developed a slight misfire, and threw an intermittent DTC on cylinder 2.
Swapped the coil packs from 1 to 2 and misfire still there thought it does appear to have moved to c1 (pointing to the coil pack being the issue) but no DTCs but it still won’t rev over 4000.
Will replace the pack this week but what would cause the 4000 rev limit - hoping it’s not symptomatic of a lifter issue. 108k kms.
