Thread: Disco TD5 running rough

Yesterday on my way home from work my TD5 started running rough almost like it was running on 4 cylinders and not 5. Vibrations where apparent when the car was idling, accelerating and cruising. For as long as I have owned the car it has not overheated, nor has it lost any oil...

Coolant on the other hand i noticed a small leak on Friday. wasn't loosing much coolant maybe 100ml max under the car. I subsequently spent time under the car trying to chase and identify the source of the leak. For which I have been unsuccessful in identifying a clear source for the leak.

At this stage I am thinking that the following could be the root of my problems:

1. There is an issue with one of the sensors, thus the computer is affecting how the motor performs.
2. I have done a head or head gasket. (I have not noticed any white smoke from the exhaust)
3. Fuel pump playing up.
4. Injectors are faulty.

What do you guys think?

I'll keep you posted as to what I discover after I run a computer diagnostic on it.

Had the same a month ago. Start up and initial idle ok. Within 2mins intermittent rough (4 cyl?) idle. Was the injector harness -as suggested by others.
