Swerve indicator comes on for no reason.,

I would scan for codes. There may be a sensor that has gone bad.

For sure, scan it. My dodge does that too. I got a vacuum leak and computer thinks it's something worse. Its throwing your car into limp mode.

Hell, could be a vacuum leak actually..take look with it running, see if you can hear anything. We have the same engine I'm betting. Check your egr favor tube too. That one LOVES slipping past its seating area

Master Pro Ignition 3 Terminal Camshaft Position Sensor the part and under $40 dollars. I have 2008 Magnum and mines kept coming on until i changed it out.
