Solution

1. Preparation

Gather tools and parts needed for repairs.
Disconnect the battery to ensure safety while working on electrical components.

2. Clean or Replace Throttle Body

Remove the throttle body from the intake manifold.
Use a throttle body cleaner and a soft brush to clean the inside.
If damaged, replace it with a new throttle body.
Reinstall the throttle body and reconnect any electrical connectors.

3. Inspect and Replace Fuel Filter

Locate the fuel filter along the fuel line.
Release fuel pressure by loosening the fuel cap and using a fuel pressure gauge.
Remove the old fuel filter and install a new one, ensuring correct orientation.
Reconnect fuel lines and check for leaks.

4. Replace Spark Plugs and Ignition Coils

Remove the ignition coils by unscrewing them and disconnecting the electrical connectors.
Replace the spark plugs with the manufacturer-recommended type and torque them to specifications.
Reinstall ignition coils securely.

5. Check Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If low, add the manufacturer-recommended transmission fluid until it reaches the proper level.
If the fluid is burnt or contaminated, consider a transmission fluid change.
