Oil on plugs

619 Views 2 Replies 3 Participants Last post by  mexrs
I got a code for the car running too lean, it said either change the plugs or coils so I obviously chose the cheaper option to see if it would do it and I went to change the plugs, the first one is completely covered in oil to the point of dripping.
They are denso plugs which leads me to believe they have been changed before me

it has 37k miles
