Anyone with 3.0D had any drivability issues? I have 850 miles on mine. Am traveling the US, towing behind my RV. Got to Vegas, unhooked...went cruising and lost throttle response and started surging. Pulled over. Shut off engine. Restarted engine. No issues. Went another 20 miles, same thing. Local dealership came and got it with a rollback. After sitting a day there, they said EGR tube plugged. 2 weeks to get another one. I am leaving for Cali tomorrow.
