Welcome to the addiction,
first read through this, it contains a wealth of information for new owners of a Jeep CRD.
viewtopic.php?f=5&t=54207Basted on the little information you supplied, it does sound like you may be having a low boost issue.
There are many reasons this can happen, but would need more information to offer suggestions for solving the problem.
DTC's (check engine light) would be a good start to help diagnose if you have any.
Feel free to ask questions after you have read through the NOOB Guide, lots of very friendly, helpful, and knowledgeable members on this forum that are more than willing to help.....
