Thanks meme. I think it is the accumulation of dirt collected from the filter. When I sprayed it with K&N filter cleaner, the dirt oozes out like very old sticky grease. The plenum had some thin coat of brownish deposit but surprisingly cleaner than I expected. I knew I am due for a TB clean. My idle is not rough but I noticed increased tendencies of hesitation when pressing the gas. After the cleaning it, I noticed more responsive and quicker response on the gas.
Other than that, the car is babied, garage kept. The slightest issues, I can't rest easy until fixed or resolved. I am so anal about it that I don't allow anybody eating chips in the car and as much as possible don't want to carry cooked food in the car.
