Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Air Filter

Remove the air intake cover using a socket set.
Take out the old air filter and inspect the filter housing for debris.
Install a new air filter (ensure it meets OEM specifications) and reassemble the intake cover.
Tools Required: Socket set, new air filter.

3. Test and Replace Spark Plugs

Remove the ignition coils by unscrewing them and disconnecting electrical connectors.
Take out the spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace them if necessary.
Reinstall new spark plugs (set to manufacturer torque specifications) and reconnect the ignition coils.
Tools Required: Spark plug socket, torque wrench, new spark plugs.

4. Check and Replace Transmission Fluid

Identify the transmission dipstick and check the fluid level.
If low or burnt, drain the old transmission fluid using a drain pan.
Replace with new transmission fluid (use manufacturer-recommended type).
Reassemble the transmission pan and refill to the correct level.
Tools Required: Drain pan, new transmission fluid, funnel.

5. Check Throttle Position Sensor (TPS)

Locate the TPS on the throttle body.
Disconnect the electrical connector and remove the TPS using a socket set.
Test the TPS with a multimeter; replace if it does not provide accurate readings.
Reinstall the new TPS and reconnect the electrical harness.
Tools Required: Socket set, multimeter, new TPS.
