Nov 7, 2015 at 11:08 comment added HandyHowie Was it beyond cleaning and reusing? What you are describing sounds like the cylinder is running rich, not lean, which is the opposite of what I thought. It could still be the injector thought. Usually running rich does not ruin the plugs, they would just need cleaning.
