I am having the same problem. Mine wouldn't stay above 1000 rpm. If could get it above that it would run better. Seemed like it wanted to die when I was idling. I have had a check engine light turn on and off the past week or so.
I just changed fuel injectors because it was pouring out smoke. It helped but it is still doing a little.
I also did the glow plugs (got them from IDparts).
I also think that I have a coolant leak somewhere. But I don't ever see it on the ground. I have gone threw about a gallon this past 4-6 weeks. I did order a new overflow tank because I think it has always leaked from the tank but not nearly this much. It is not in the oil, and there is still some white smoke that comes out of the exhaust until it heats up.
ANY IDEAS WOULD BE GREAT! I am completely lost, and so is my dad....
Wow, so much going on here I dont know where to begin.
Gonna need some history on your CRD, like:
How many miles does it have
have you done the timing belt?
Who did your injector replacement?
Have you checked your turbo?
What color is the smoke when it was pouring out?
What condition were the old glow plugs when you removed them?
You say it wont rev above 1000 rpm? If thats the case you are obviously not driving it.
I suspect its due to bent/broken/worn rocker arms and/or possibly a bad turbo.
That is, of course, assuming those new injectors you installed are working properly and are
getting plenty of fuel.
Your coolant loss and white smoke indicates a leaking head gasket.
I dont know what else to tell ya. I hope when you tear down the motor its not as bad as
