Throttle Body Repair
 

Hello & Thanks in advance.

Any tips on removing and cleaning the throttle body. My game plan is to JB-Weld the leak I have and clean the MFI Sensor and any other parts that need cleaning. Any tips or links on this will be greatly appreciated.

NOTE: Clean the throttle body in a well ventilated area as the fumes from the cleaner can be very strong as well as very flammable. Safety goggles or glasses are a good idea if using a spray cleaner, brushes or compressed air. Read and follow the safety precautions on the container of the cleaner that you are using.

1. With a T-25 torx driver, remove the two screws that attach the IAC motor to the throttle body and carefully remove the motor by pulling it straight out (When looking at the throttle body straight-on, the IAC motor is on your lower right). Carefully clean the IAC motor shaft/plunger with the TB cleaner. Point the shaft downward so that residue will not run into the motor. Do not twist the plunger shaft while cleaning it as damage to the motor may result. Set aside and let dry.

2. Using a shop rag soaked with throttle body or carburetor cleaner, remove any carbon build up from the entire throttle body bore, butterfly plate and IAC shaft. A tootbrush works well to clean the corners around the plate. If using a spray cleaner it can be sprayed into the tight spots around the plate. Q-tips can also be used for cleaning but be sure to not leave any cotton fiber residue in the throttle body. Also clean the entire top and bottom surfaces of the throttle body. If desired you can use a shallow pan to place the throttle body into for cleaning. For stubborn deposits, the cleaner can be left to soak for awhile. Spray throttle body with compressed air to assist in drying.
