The above methods don't clean the injectors; similarly, fuel additives don't get the TB, EGR, or, most importantly, the IAC.

Thanks for the suggestions. I usually just remove the entire intake (sensor and all) and spray down the actual throat of the TB while opening and closing the valve using the throttle control (under the hood). When I clean the TB, I usually add FI cleaner at the same time. I hope to surpass the 200k mile point before the end of this year. I am just under 196k right now.
