Hi, Got a serious problem with our 2.8jtd MH. The fuel system warning light ( red engine symbol ) came on last week returning home from York and stayed on for about 20 miles but there was no apparent reduction in power or unusual noise and after stopping for a few minutes the light did not come on again for the last few miles home. Book says that this light indicates ' imperfect fuel injection ' which could result in reduced fuel economy and that any occasional short duration warning is 'meaningless' - take to Fiat if it stays on. This weekend the light came on again after a few miles ( when engine just getting warm ) and now comes on shortly after starting or when starting to warm up. More worrying is that the engine is now misfiring/lurching ( even at tickover ) and we only just limped home today with a real loss of power. Engine is 2.8JTD Ducato, 2004/5 and has done only 7500 miles. Has anyone any ideas of what this fault could be ?? Cheers Bill.
