go try some STP Throttle Body cleaner spray. Just use a towel to wipe it right away. Brake cleaner would work also, but I would recommend the throttle body cleaner as that is what I use to clean the internal gunk out of my Borla tips. Works well on that tar like gunk in the engine bay also if you still have any in there. Good luck.
