1. Would a faulty coolant temp sensor (Not the gauge sensor) be the problem & if so how do you test it.
2. Fuel injector rail pressure regulator be at fault
3. Faulty injectors (I don't think this is the problem - I have never seen all four injectors fail at the same time)
Any help would be greatly appreciated.
Many Thanks,
Jughead
