Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Address Airflow Issues

Replace the Air Filter:
- Open the hood and locate the air filter housing.
- Remove the screws or clips securing the housing.
- Take out the old air filter and install a new one, ensuring it fits snugly.
- Reassemble the housing and secure it properly.

3. Fuel System Inspection

Check and Replace Fuel Filter:
- Locate the fuel filter, usually along the fuel line.
- Relieve fuel pressure if necessary (refer to the service manual).
- Disconnect fuel lines from the filter and replace it with a new one.
- Reconnect the lines securely, ensuring no leaks.

4. Ignition System Repair

Replace Spark Plugs:
- Remove ignition coils by unscrewing them from the cylinder head.
- Use a spark plug socket to remove old spark plugs.
- Inspect the old plugs for wear; install new spark plugs with the specified gap.
- Reinstall ignition coils and torque to manufacturer specifications.

5. Transmission Fluid Check

Inspect and Replace Transmission Fluid:
- Locate the transmission dipstick and check fluid levels.
- If fluid is low or discolored, drain the fluid using a pan and replace it with the manufacturer-recommended transmission fluid.
- Refill to the appropriate level through the dipstick tube.

6. Exhaust System Check

Inspect and Clear Exhaust Blockages:
- Check the exhaust system for physical damage or restrictions.
- If the catalytic converter is suspected to be clogged, consider replacing it following manufacturer specifications.
