Anyone had this code before? Got it once a few weeks ago hauling a load of wood on the trailer down the road got it as soon as I was pulling out of the driveway. I got it again today empty heading home. I noticed this morning on the way to work my throttle seemed a little more lag than normal but just figured it was the cold fooling with it. I checked the crank case hose as suggested by another post on here and checked all my vacuum lines. I noticed at an idle if I take my oil cap off it seems to be a little bit of a positive pressure coming from it. Oil looked fine, 3k on it and looked fairly clean for what it is.
