Solution

1. Preparation

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

2. Replace Spark Plugs

Remove the ignition coil or distributor cap (if applicable).
Using a spark plug socket and ratchet, carefully unscrew the old spark plugs.
Inspect the spark plug electrodes for wear.
Install new spark plugs, hand-tightening them first then torque to manufacturer specifications (usually around 13-15 lb-ft).
Reconnect the ignition coil or distributor cap.

3. Check and Replace Fuel Filter

Locate the fuel filter and relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter, being cautious of residual fuel.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and replace the fuel pump fuse.

4. Inspect and Replace Air Filter

Open the air filter housing by unclipping or unscrewing it.
Remove the old air filter and inspect for dirt or blockages.
Install a new air filter, ensuring it fits snugly in the housing.
Reassemble the air filter housing.

5. Check Transmission Fluid

Locate the transmission dipstick (if applicable).
Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
If the fluid is low, add the appropriate type of transmission fluid as specified in the owner's manual.
If the fluid is discolored or has a burnt smell, a transmission fluid change may be necessary.
