crabots Posted October 31, 2012 Share Posted October 31, 2012 Hi, Briefly, the Disco runs normally in traffic (low engine speed/low throttle openings). On the open road, after driving at 50/60mph, if you take your foot off, the engine “dies” on deceleration. Jigging the throttle produces thick dirty greyish smoke but it won’t pick up. When it eventually does (sometimes have to pull over first), then runs normally till next deceleration point…..Help!!! Engine oil level has remained static for last 3000 miles+, there is no sedimenter or EGR fitted and its not ECD. The engine always starts on the button and never smokes under other circumstances I tried something today, which I think may narrow the problem to the injector pump…Was driving at about 3500rpm (on straight road, no traffic etc.) and I switched off the ignition (and so pump stop valve). I didn’t touch the clutch but allowed vehicle to slow under engine braking until about 1500rpm. Then Switched on ignition and pushed throttle pedal and the vehicle pulled away with NO HESITATION and NO SMOKE! Could this point to a problem within the pump? Advance mechanism? Boost compensator? Loose drive pulley, or something else sticking??? Please, if anyone has suggestions it would be appreciated. Quote Link to comment Share on other sites More sharing options...
