eng light on, car jerks,stalls on drive reverse, but will drive once started on 2004 Chrysler Sebring

The car was running great until the 26 below temp hit us.
Engine jumped motor mount, and engine light came on. Lasted for a week and went out. Weather got cold again and light came on again and remained. Once the car was warmed, it would stall then jerk and take off. Stalls in traffic sometimes. Other times if weather is good, it takes off without a problem.
