Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, socket set.
Remove the intake duct connected to the throttle body.
Spray throttle body cleaner onto a soft cloth and wipe the inside of the throttle body, removing any carbon deposits.
Open the throttle plate manually to clean behind it, ensuring no residue remains.
Reconnect the intake duct securely.

3. Inspect and Replace Air Filter

Tools Required: None (if no special clips are present).
Locate the air filter housing and remove it.
Take out the old air filter and inspect it for dirt and damage.
Replace it with a new, clean air filter.
Reassemble the air filter housing.

4. Test and Replace Throttle Position Sensor

Tools Required: Multimeter, socket set.
Disconnect the electrical connector from the TPS.
Use the multimeter to check the voltage output of the TPS while slowly moving the throttle.
If readings are inconsistent or outside the manufacturer's specifications, replace the TPS with a new part.
Reconnect the electrical connector securely.

5. Check for Vacuum Leaks

Tools Required: Smoke machine or carburetor cleaner.
Visually inspect vacuum hoses for cracks or disconnections.
If available, use a smoke machine to detect leaks; repair any damaged hoses.
Alternatively, spray carburetor cleaner around the intake manifold while the engine is running to identify any changes in RPM, indicating a vacuum leak.
