Ok, so I'm new here and new to BMW's in general (been a Jeep guy for a while) but I picked up a 1985 325e fairly recently and I've been having some issues with it. I checked the forum and didn't find any issues exactly like mine. So, the car for the most part will start up fine, but not long into driving it the idle starts to bounce a little. Not a lot, Maybe from 400-600 rpm, but it gets worse and worse until the car starts shaking and bucking while it's in gear and then it just shuts off. It won't start back up after with the key (no noise at all from the starter, almost like a dead battery), but it can be bump started, although it won't run for long and the same issues arise.
The car sat for some time during its life, so I replaced both fuel pumps and the tank because they were in really bad shape and I thought that's why it was dying, but the problem continues. Sometimes it will start back up if it's left overnight, sometimes it won't, and most recently I had to call a friend to come help me after it died in the road while I was testing the new pumps. This time it started back up after we attached a battery booster, but the idle problem was still there (although I was able to make it back). I'm thinking it could be the alternator, but I wanted to see if anyone has had these same type of issues before.
