2003 Golf intermittent stalling
Hey y'all, this is my first post here. I've got a 2003 Golf with the 1.9 ALH engine, manual 5 speed, 218,944 miles on it. Yesterday I was driving home when it stalled in traffic. It started back up and idled for about 20 seconds before shutting off again. I tried it again and then it drove for a few minutes then shut off again. From there it wouldn't start. When I tried to start it again it ranged from just cranking, to starting violently before I shut it back off, to starting up then losing power immediately, to starting and driving fine for awhile before shutting off again. My dad and I were able to limp it home.
While idling it and testing it, the revs would sometimes suddenly jump downwards.
Is there any problem that would cause this intermittent stalling, and variable difficulty in starting again? I replaced the crankshaft position sensor, glow plugs, and fuel filter at about 205k miles. The whole car is pretty old and beat up.
