got a prob with my 2000 jtd .this is something that has happened 3 times in 7 mths. the injector light comes on and although the engine is still running it looses power and emits black smoke from the exhaust only when it was reved up.
called out the rac he plugged in the diagnostic and it showed no code just a fiat sign. it is running fine now but would like to sort it before the summer and caravan towing.
