Drove to the grocery store parking brake up and must of knocked the car into gear when getting out. When I turned the car on when I returned I let off the clutch and the car stalled of course. Turn it back on and engine maintenance light comes on and entire car shudders at idle. Drive it the couple miles back home with random shuddering and weird acceleration issues. Did I kill my car? I have trip to Colorado planned in a couple weeks and was counting on my car. Service dealer isnt accepting any new appointments at the moment. Will of course take it first thing tomorrow morning anyway. Just looking for some advice. Sounds uncomfortably similar to some recent issues addressed here. Thanks all!
