You can do it on the vehicle. Remove the air pipe from the filter housing to the throttle body and you should have just enough room to get to it. Have a helper hold the engine up around 2-2.5k rpms and spray it out. Of course once the pipe is off, it's only 5 easy bolts to remove and one electrical connector to remove the TB too. You can easily reuse the o-ring gasket on it too.

 

@Patriot_69, if you want to see what's involved in removing the air pipe, there are several youtube's on throttle body removal that will give you a good idea.

 

Hi did cleaning the throttle body help?
