This is a diesel? I know with regular fuel vehicles, the MAF/MAP sensor could cause these problems.

This sensor is located on the intake tube. They make cleaner for this part but it's usually smarter just to replace it.

Try disconnecting the harness on this sensor, start vehicle up, and see how it idles. If it idles smoother, that's your problem.
