Swerve indicator comes on for no reason.,
I start my car and the swerve indicator warning comes on and stays on. This forces the engine down to 35 mph. It does this for no reason from a dead start.
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
