Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical shorts.

2. Clean or Replace Throttle Body

Remove the air intake hose connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Reinstall the air intake hose and reconnect the battery.

3. Replace Air Filter

Locate the air filter housing and remove the cover.
Remove the old air filter and inspect for dirt or damage.
Install a new air filter, ensuring it fits securely, and replace the housing cover.

4. Check and Replace Fuel Filter

Locate the fuel filter; it may be in-line or integrated into the fuel pump.
Relieve fuel system pressure before removing the filter.
Replace the old fuel filter with a new one, ensuring proper orientation and secure connections.

5. Inspect Ignition System

Remove the spark plugs using a socket set and inspect for wear or fouling.
Replace worn or damaged spark plugs with OEM-spec plugs.
Check ignition coils for damage; replace if necessary.

6. Inspect Transmission Fluid

Locate the transmission dipstick and check the fluid level and condition.
If fluid is low, add the appropriate type of transmission fluid to the correct level.
If fluid is burnt or contaminated, consider a transmission fluid change.
