Just so there is no confusion, the Jeep CRD has no throttle valve.
Some members in the past have advised strongly against spraying any kind of intake cleaner into this engine. Seafoam, Mopar, and several others make spray intake cleaners.
In past discussions, thoughts were that once you remove or totally disable the EGR system, the oily mist and vapor coming from the CCV system will eventually clean out the gooey soot buildup in the intake manifold since you no longer have soot being dumped into the intake. This is provided you still have the CCV hose connected to the turbo intake boot like it came from the factory as it should be.
If you do a search on LOST, there are some threads with discussions on these subjects.
Short of pulling the intake/valve cover manifold and soaking/flushing it, there are very few other options.
