I have the JTD 1.9 diesel 3dr Stilo and about two weeks ago, I was accelerating, in 3rd gear, about to shift into 4th and I was just under 2500 revs when this alarm rang with "Engine Fault" appearing on the LCD screen?? WTF does that mean, any suggestions?? Anyway, the fault indicator disappeared just as quick as it appeared. But this morning, it all happened again, but this time the car dropped in speed. Could it be the turbo? Fuel lines/filters? Glow Plugs? Timing/Tuning? Any Suggestions??
