White plugs mean its running too hot. High NOx. Lean condition. I bet your CO is low -- around 0.10 or lower, too. Replace the plugs to spec and clean the EGR passageway while you're at it. After you clean the gunk out, apply vacuum with a hand pump to the EGR at idle. The engine should stumble if the EGR is working. If not, it's either still clogged somewhere or the diaphragm is broken.
An good call Sir, predicated of course upon the O/2 readings...or CO/2 readings.Originally Posted by noahwins
