I got a 94' b4000. My EGR gas tube is full of holes and makes a bad exhaust leak sound when I drive. A new tube is 140 at napa will buy eventually but about to embark on at 1000 mile drive. Does the tube having holes effect the performance? Also, can I take if off the manifold and plug the port? If so, what will that do to performance, mpg..?
