1996 Montero/ Pajero - Bad start/ none idle
 

Hello
I have a Pajero/Montero 2,5GLX (4D56TD) -96, with some idle problems.
It starts badly, and will not idle when it gets warm.
It must have a rmp at 1500-2000 to idle, and not even then it gets the power it used to. Not very handy in intersections etc...
Anyone out there with some suggestions of the problem?
Maybe the diesel-filter? Diesel-pump (hope not)? Any leaks?


Thanks in advance!
