So I haven’t driven my 2003 Jetta in about a week and a half. Today when I started it it struggled to start, and then at a stop light while my foot was on the brake it was jumping/stuttering. it continued when I moved at 5 mph, but did not happen while driving at higher speeds (15 mph) and went away when j shifted from drive to park. I got on the highway and drove for 15 minutes with no issues, and now the problem is gone. Is this a sign of a failing part?
edit: the spark plugs and wires were replaced 6 months ago. I had them changed because the car has always had a small intermittent rough idle that would sometimes happen when stopped and at low parking lot speeds, but it’s never been so noticeable. it was really lunging this time
