Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, throttle body cleaner, and safety glasses.
Disconnect the negative battery terminal to ensure safety during the repair process.

2. Inspect and Clean Throttle Body

Remove the air intake duct to access the throttle body.
Detach the throttle body electrical connector and remove the throttle body mounting bolts.
Carefully pull the throttle body off the intake manifold.
Clean the throttle body using throttle body cleaner and a soft cloth to remove carbon deposits.
Reinstall the throttle body and reconnect the electrical connector.

3. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter in the fuel line (refer to service manual for specific location).
Relieve fuel system pressure by disconnecting the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the old fuel filter using a line wrench.
Install the new fuel filter, ensuring correct orientation and tightening the fittings securely.

4. Inspect Spark Plugs

Remove the ignition coil or spark plug wires to access the spark plugs.
Use a spark plug socket to remove each spark plug.
Inspect the spark plugs for wear, carbon buildup, or damage.
Replace any faulty spark plugs with new ones, ensuring proper gap settings are followed.
Reinstall the ignition coils or spark plug wires.

5. Check Transmission Fluid

Locate the transmission dipstick (if equipped) or check the fill plug.
With the engine running, pull the dipstick and wipe it clean, then reinsert and remove again to check fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.
If the fluid is dark or burnt, consider a transmission fluid change.
