300E Starting and running problems
Strange happenings with 1987 300E. Recently had tune-up, mechanic said I needed new distributor cap. Drove car 500 miles or so. Now car quits running and won't start after about 2-3 minutes. Cranks OK just won't fire. Seems to run fine while it is running, but will just quit unexpectedly. Would this be a cap or should we look for something else???
