Change the plugs, Make sure you are getting ignition from the coils and inspect the egr equiptment! Then once you are done with that we can try to pinpoint it better

I have heard some people say to do have a valve adjustment and leak down test performed. There are quite a few missfire threads going around.

Your in "Under the Hood"Forum. People here can help but you have to give them half a chance. Above are listed all the DTC codes for the Primary and Secondary O2 sensors.

So how about a hint as to which code you threw before you added in all the other variables.
