Question about 2008 Mercury Mariner
TBI is the part where the plastic duct coming from the air filter housing mates the engine. The part where the clamp attaches on the engine side is the TBI. The TBI has attached the Throttle Position Sensor TPS and the Air Intake Control Valve AIC,
A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Throttle body is the part with the big opening you see below. If you ae having rough idle issues, clean out the throttle bore with carb cleaner and a rag. You may want to also take the idle air control valve off and clean the passages there too.
This picture is for the 2.4 liter engine, but the 3 liter is similar. Let me know if you have questions.

what u do is go to your local auto supply store and buy throttlebody cleaner you remove the rubber hose from the throttle body with the engine off of course u open the throttle and spray cleaner in it then use a tooth brush inside it replace the hose done
except it will be hard to start the first time crank engine over with foot to the floor on the gas pedal do not pump it

You can either clean it on the truck or off, better off of the truck, that way you can get both sides. Take off the black tube coming from the air filter housing, if your going to take the whole thing off the truck, you will need to disconnect the throttle cable from the housing. There should be 4 bolts holding the body onto the intake. Get a can of fuel injection air intake cleaner, spray it in the body and on the plate, wipe dry with a clean cloth. Repeat until clean. When you start the truck back up, it might sound like it's miss firing, don't worry, it will clear up.
