Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid electrical hazards.

2. Replace Fuel Filter (if clogged)

Locate the fuel filter (usually near the fuel tank or along the fuel line).
Use a wrench to disconnect the fuel lines from the filter.
Remove the old fuel filter and install a new one, ensuring correct orientation.
Reconnect the fuel lines securely and check for leaks.

3. Clean or Replace Air Filter

Open the hood and locate the air filter housing.
Remove the cover and extract the air filter.
Inspect the air filter; if dirty, clean it or replace it with a new one.
Reinstall the air filter and cover properly.

4. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires to access the spark plugs.
Use a socket wrench to unscrew the old spark plugs.
Check the gap on new spark plugs and install them, ensuring they are torqued to manufacturer's specifications (usually around 13-15 lb-ft).
Reconnect the ignition components.

5. Evaluate Exhaust System

Inspect the exhaust system visually for any damage or blockages.
If a clogged catalytic converter is suspected, perform a backpressure test.
Replace or clean the catalytic converter if necessary.
