The frequency valve is about 4" to the left (driver's side) of the throttle body, about 4" above the fiberglass shroud.
The lambda system is designed to keep your mixture close to stoich (14.7 to one) all the time except at full throttle and during cold start and warm up.
If you leave it connected and everything is adjusted and functioning correctly, your engine will run clean, smooth, and with near maximum efficiency. If you disconnect it and adjust the CO to around 3 to 3.5, you will get more power and sacrifice economy and clean running.

Why do you want to remove it completely? I see no reason to remove it, just disconnect the O2 sensor and the frequency valve goes to default setting. then adjust for CO and you are there if that is what you are after.
