Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle's battery to ensure safety during the repair.
Tools Required: socket set, screwdriver, multimeter, cleaning supplies (compressed air, throttle body cleaner).

2. Inspect and Clean Throttle Body

Remove the engine cover (if applicable).
Locate the throttle body assembly.
Use throttle body cleaner and a soft cloth to clean the throttle body, ensuring no carbon buildup is present.
Check for any signs of wear or damage on the throttle plate and housing.

3. Inspect Throttle Cable

Locate the throttle cable connected to the throttle pedal and throttle body.
Check for kinks, fraying, or obstructions along the length of the cable.
If damaged, remove the cable from the throttle body and pedal assembly, and replace it with a new one.

4. Verify Throttle Position Sensor

Locate the throttle position sensor (TPS) on the throttle body.
Using a multimeter, check the voltage output of the TPS while manually moving the throttle plate.
If the readings are inconsistent or outside manufacturer specifications, replace the TPS.

5. Reassemble and Test

Reconnect any components removed during the process.
Reconnect the battery.
Start the vehicle and ensure the throttle operates smoothly without sticking.
