We've been having a intermittent rough idle/shuddering at stop lights that has been getting progressively worse. Today, CEL finally came on. Dealer says it is a misfiring cylinder. This just a few weeks after we got the JGC back from the CV boot saga.
Has anyone got any ideas of what could be going on? Truck now has 825 miles or so. Could it be a problem with the common rails and in particular, maybe the injector?
