Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat, stable surface.
Disconnect the battery to prevent electrical shock.

2. Check and Replace Spark Plugs

Remove the spark plug wires or coils (using a socket set).
Use a spark plug socket to remove the old spark plugs.
Inspect new spark plugs for correct gap size and install them (torque to manufacturer specifications).
Reconnect spark plug wires or coils.

3. Inspect and Replace Fuel Filter (if applicable)

Locate the fuel filter; it may be under the vehicle or in the engine bay.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect fuel lines from the filter (using appropriate line disconnect tools).
Replace the old filter with a new one, ensuring correct flow direction.
Reconnect the fuel lines and reinstall the fuse.

4. Clean or Replace Air Filter

Locate the air filter housing and open it (using a screwdriver or socket set).
Remove the old air filter and inspect for dirt or blockages.
Install a new air filter, ensuring it fits securely in the housing.

5. Test Drive and Recheck Fluid Levels

Reconnect the battery.
Start the engine and allow it to warm up.
Test drive the vehicle under conditions similar to the original problem.
Check the transmission fluid level and top off if necessary.
