jondmn 4/1/2010You are burning oil. How its getting there is the question. Could be coming around the rings or through the valve guides. You could also be getting some through your EGR system. I would start with changing out the EGR valve, and the O2 sensor,this will probably take care of the idle and rpm problems. Have someone do a compression check on it.
