Just bought a 1999 L400 (auto diesel). Driving it home on the Highway realized the engine starts to "surge" while cruising around 90 km/hr. Doesn't seem to do this at any other speed or while accelerating.
The surging feels like the engine loosing power briefly and repeatedly , I have had a similar feeling from vehicles under acceleration that needed new spark plugs.
Any ideas where to start here?
