Rough running above 2000rpm.

[Naraic]

Well it had to happen, after nearly 6 years without a problem I am here to say...I may have a problem...but not with the hydraulics.

I have felt the car being rough lately and felt it was drive train related...but to-day I tested the engine at standstill asnf the engine is rough at and above 2000rpm.

Suggestions?

The engine is m113 5l.

I dont have a cl500.
I reckon it is lack of fuel at the higher revs. Fuel filter/pump..?
