I need some instructions on how to clean the throttle body on the Q. I have the service manual, but I could not find any information on how to clean the throttle body. I have searched the forum but I still have a couple of questions.

Do I leave the engine running while I spray the throttle body cleaner?

How do I manually move the butterfly back and forth?

Thank you much.

here's one more. probably better to manually clean the TB. carb cleaner and lots of rags. both sides of the butterfly. use a flash light to see the tough places. an assortment of small brushes (toothbrushes), will help, toojeff

Thanks for the links NuQ.

I am glad I did it because it was very dirty.

What I missed from all the information on cleaning the throttle body was how to make the butterfly plate open. I finally figured that out by push down the throttle cable.

Sorry for all the newbe questions

You should be able to carefully wedge a screwdriver into the throttle cam. At least that's how I do it on the J. Don't know if it's the same set up on the Q.
