Hoping this will fix my sluggish 240 if I clean it. Anyone know where it is?

that metal tube thing that's attached to your air box. It will have a plug on the side of it with 4 connectors on the inside of the plug. Take some carb or brake cleaner and spray it in there, not directly on the hotwire though, as the pressure may damage your sensor.

You can clean the hot wire with electrical parts cleaner. Just make sure it's unplugged whenever you do.
