I have a 2007 300 Limited. The throttle body was cleaned two months ago and not the Electronic Throttle Control comes on when I make a left turn too sharply. The traction control light also comes on. I took it to Park Jeep, and they didn’t find anything wrong. They cleared the codes and that was that. However, the lights still come on. When it does the idle speed picks up. When I restart the car, things go back to normal until the next hard left turn. Is it a drivetrain issue, or throttle body gasket? What should I tell the dealership to do?
