Cleaning N/A throttle body

[evinX]

So on and off, my supra likes to hunt and it does my head in. Ive found out that a dirty throttle body could be causing this? has anyone done it? Ive been told I need to remove the intake pipe and spay some carb cleaner in there while running.

 

Was going to use this stuff

Can anyone give and tips on doing it and is it worth it?

 

thanks, Kev
