Sys. to lean bank 1 and 2, caused by bad rubber gromets around the bolts that attach the upper intake to the lower. these are damaged by the oil and fail over time they are black in color you will want to get the green ones that stand up to oil, etc. Go to a junk yard and pick some up for a few bucks or go to ford and pay $10.00 for each one (eight required)
