- HEMI 5.7L
Vehicle: 2014 1500 with 150k miles (5.7L HEMI)
Issue: at cruise (7th or 8th gear, 70mph on the highway) my engine has started a "tachometer hiccup" about every 4 seconds (very constant cadence) where the engine will increase RPMs by ~100 for a split-second then return to normal. I've capture about 10 seconds of it via TORQUE below.
Anybody experience this?
