Hi there.
'96 Discovery 300 tdi auto, 123300 miles. Was driving to work this morning when engine started to drop revs. Town driving at the time - revs going between 1200 -1800 rpm driving along road with speed bumps. Engine started to drop revs every 15 secs or so. Started paying attention and saw white engine warning light flicker on, while revs dropped. This continued while driving at low speed. Problem resolved itself after cleared speed bumps. Anyone got any ideas what was going on. Is there anything 'imminent' that I should watch out for? Suggestions welcome. Thanks Davy M.
