Over time, carbon deposits accumulate in the throttle body, which can hinder vehicle performance. You might notice several dirty throttle body symptoms indicating that it’s time to replace or clean the part.
In case of a damaged throttle body, your best option is to replace it. Visit Auto Parts Warehouse for a quality replacement throttle body: https://bit.ly/2wNsvrj
Signs of a dirty throttle body:
- Rough engine idle – The engine feels shaky while idling.
- Uneven engine acceleration – stuttering engine or slowed acceleration
- Engine light comes on – “Check Engine” light turns on when the control module detects a problem in the throttle body.
- Poor fuel economy – You get fewer miles to the gallon than your vehicle’s usual mileage.
Where is the throttle body and how does it work?
The throttle body is usually found between the air cleaner and the intake manifold. It’s connected to the gas pedal using a linkage or flexible cable, which in turn moves the shaft when the gas pedal is released.
Check your owner’s manual if your throttle body is manually or electronically operated before cleaning. Electronically controlled throttle bodies are highly calibrated and delicate, so the best option is to remove it completely and have a certified mechanic do the cleaning.
How to remove the throttle body:
Step 1: Remove the throttle body shell.
Step 2: Remove all electronic connections attached (usually one on each side and one in the back).
Step 3: Remove the vacuum line from the front.
Step 4: Remove the actual throttle cables (Do not pry these connectors; they are usually connected by a “C” connection).
Step 5: Remove all bolts that are holding the throttle body in place.
Step 6: Remove throttle body. Mind that many sensors are connected to this part of the vehicle and can be reused.
Cleaning the throttle body while on the vehicle (manually-controlled):
Step 1: Remove the battery cables from the terminals.
Step 2: Disconnect the clips attached to the air filter cover, mass airflow sensor, and intake tube and remove them.
Step 3: Remove the air intake hose by loosening it until it slips off the throttle body.
Step 4: Remove the entire air intake housing from the engine compartment.
Step 5: Replace the air filter to ensure your engine’s efficiency.
Step 6: Spray throttle body cleaner inside the throttle body intake, including its blades and housing, then let the cleaner sit for a while.
Step 7: Spray cleaner on a clean towel and wipe the entire surface. Carefully wipe the throttle blades.
Step 8: Once done, inspect the edge of the throttle body, blades, and control valve for carbon buildup or damage.
Step 9: Reinstall the components.
