1983 240d misfiring at high speed
265k miles, love this car. Recently started misfiring at high speed on highway - up around 80 I could feel & hear it. Problem seems to be getting worse - now up any kind of grade over 60mph it's really starting to sputter. I had it in for service about a year ago where I'm pretty sure the filters were changed - read it could be an injector or pump problem or worst case compression.. Any experience or suggestions most welcome. Thanks!
