Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety during the repair process.

2. Addressing Fuel System Issues

Check Fuel Filter:
- Locate the fuel filter and remove it using a socket set.
- Replace with a new fuel filter using the manufacturer-recommended part.
Inspect Fuel Pump:
- Remove the access panel to the fuel pump if necessary.
- Disconnect the fuel lines and electrical connector.
- Replace the fuel pump if it fails the pressure test.

3. Inspecting Ignition System

Replace Spark Plugs:
- Remove the ignition coils using a socket set.
- Use a spark plug socket to remove old spark plugs.
- Install new spark plugs, ensuring they are gapped correctly (refer to manufacturer's specifications).
Check Ignition Coils:
- Use a multimeter to check the resistance of each ignition coil.
- Replace any faulty coils with new ones.

4. Air Intake and Sensors Inspection

Clean or Replace MAF Sensor:
- Disconnect the MAF sensor and inspect for dirt or debris.
- Clean the MAF sensor with MAF sensor cleaner or replace it if necessary.
Inspect Air Filter:
- Remove the air filter housing cover and inspect the air filter.
- Replace the air filter if it’s dirty or clogged.

5. Exhaust System Inspection

Check Catalytic Converter:
- Inspect for physical damage or signs of overheating.
- Perform a backpressure test to confirm if the catalytic converter is clogged.
- Replace if necessary.
