I am going to be cleaning my throttle body soon. Should I remove the entire throttle body and then clean it with the spray or should I just clean it with the spray while it's still on the car? If I remove it, How do I know what torque to tighten the bolts at?

Also, other than the air intake pipe and the electronic connector, what other connections need to be removed from the TB?

Thanks

 

If you're gonna clean it, might as well do it right and remove it and clean it thoroughly off the car and then re-install it. Not sure what you need to torque it back down to or what else you might have to remove though, maybe someone else knows.

 

those 4 bolts are 7 ft/lbs, but you dont have to take the throttle body off. you could if you'd like to, but almost all the shops just leave it on and clean it.

 

Take pics before the cleaning and after. Here's what mine looked like with 35k miles :

 

Here you go

 

How often should throttle body be clean? Does it just involve spraying it inside and then starting up the car and reving it a few times?

 

removing the whole throttle body is not necessary. just get throttle body cleaner spray, a rag and a old toothbrush. spray some in there clean with the rag. push the cover open and use the toothbrush. make sure you spray some in there and rev it up hard.
i would clean it everytime i change my air filter.
