went for a drive tonight and the CEL was gone did not erase them.
the car had a new right cam put in by the PO under waranty. hope this is not related.car has no more waranty
Thanks
what can this be
Lean at idle might stem from the charcoals being out or the oil dip stick not being seated properly. The incorrect cam shaft position might be from dirty oil.
