Just to let you guys know .... stretched timing chain was the culprit with my 3.3 (115k). Code 11 never dropped because it only drops during start mode and not run mode.
FYI, you can check slop in the chain by dropping the oil pan. My chain had almost an inch of side-to-side slop which translated to over an 1/8 inch sprocket rotation play. New chain has very little slop and virtually no sprocket play.
