Hello,
I've Had my SRT6 for the past 4 months or so and started getting this problem recently. Every once in a while the check engine light would come on, and sometimes in those instances, the car would feel like it goes into limp mode. The car doesn't go above 1000 RPM, it shakes, almost like there is a misfire. Usually turning off the car waiting a sec and turning it back on fixes the problem and I'm on my way.

UPDATE: The only code read so far is a P0410. The check engine light went away however the same problem still persists.
