Have a day off so got a couple jobs done that were overdue. It’s been down on power and lumpy at idle. The spark plugs were 65k miles old and well overdue replacement. I also decided to clean the throttle. The top photo shows some of the deposits on the throttle, this was after I started cleaning.

It was full of oily junk and probably part of the reason I was having issues. Car runs much smoother now so I’m calling it a job well done.
