Solved...Its always the simplist of things that keep you guessing.

Background. Like I said in previous post. I had my plugs and wires changed out a while back. This all happened due to a leak into the spark plug holes, so the mechanic changed everything. New Vavle Cover gaskets, new seals on the plug tubes, new plugs, new wires, and just for fun, the PCV valve.

Well everything went to plan until he had to redo the vavle cover gasket, due to another leak. During this he put the PCV vavle in BACKWARDS <img src="/forums/images/graemlins/rolleyes.gif" alt="" />. This whole time my truck ran like junk due to an $8 part that was put on wrong. Well now my truck runs great and even a little better due to the new High Flow CAT.
