Took the opportunity to clean the throttle body with CRC Throttle Body & Air Intake Cleaner.
To my surprise my throttle body still looked great on the engine side with 63.5k miles and the last 21k with oiled K&N Air Filter. People are always heavily opinionated how much that product gunks up the throttle body and the mass air flow sensor. But mine looked fine. I had to take the throttle body off to get to the power steering pump (suction pipe O-ring replacement). Glad I cleaned it all out.
