Cleaning your Throttle Body...
THROTTLE BODY CLEANING
1. Start the engine and warm it up until the coolant is heated to 80*C(176*F) or higher. Then stop the engine.
2. Remove the air intake hose from the throttle body.
CAUTION!!! DO NOT ALLOW CLEANING SOLVENT TO ENTER THE BYPASS PASSAGE.
3. Plug the bypass passage inlet of the throttle body.
4. Spray cleaning solvent into the valve through the throttle body intake port and leave it for approximately 5 minutes.
5. Start the engine, rev it several times and then idle it for about 1 minute. If the idling speed becomes unstable (or if the engine stalls) due to the bypass passage being plugged, slightly open the throttle valve to keep the engine running.

I have some questions....
How much of the cleaner do I spray in the TB? The whole can?
When you spray the cleaner in the throttle body, does it flow into the combustion chambers? If so, can I spray cleaner in the cylinders through the spark plug wells?
