hey all..... I have a 2005 jeep liberty diesel, have owned it 2 years in march of 2013 and loved it until recently. been having some excessive unburned fuel dumping out of pipe. i have replaced the fuel filter/ heater element assy. twice and this has not helped. i have replaced 4 injectors at the dealers diagnosis and there is still black smoke? and there is a nocking noise in the engine when you get rpm above 2200. any ideas??????

Post here about it and you might get a better response.

Welcome to the forum. You may want to head over to the CRD forum. First, read Sir Sams Noob guide. That is the first thing I did. Any questions asked there will be answered by people who own CRDs.
