My 87 has a slow, steady "lope" at idle. It is not really a miss, can't feel it from the driver's seat. If I put it in drive it almost completely goes away, and raising the RPM slightly also makes it go away. New delivery valve seals, new vacuum pump, motor mounts, glow plugs, belt and tensioner system. The lope was there before all the new parts and was even more noticeable as it was causing a vibration/noise which I think was the two piece shroud which was broken. The first video is in Park, the second in Drive. You can see the stop lever rising and falling with the "lope", which I assume is an effect rather than a cause? Any ideas where to start?
