Solution

1. Preparation

Gather tools and parts necessary for the repair.
Disconnect the battery to ensure safety while working on the vehicle.

2. Address Ignition Issues

Inspect Spark Plugs:
- Remove spark plug wires and unscrew spark plugs.
- Check for wear, carbon deposits, or damage. Replace if necessary.
Check Ignition Coils:
- Disconnect electrical connectors from ignition coils.
- Remove coils and test with a multimeter for proper resistance. Replace faulty coils.

3. Assess Fuel System

Inspect Fuel Injectors:
- Remove the fuel rail and inspect injectors for blockages.
- Clean or replace injectors as needed.
Check Fuel Pressure:
- Connect a fuel pressure gauge to the fuel line.
- Verify that fuel pressure meets manufacturer specifications (typically around 30-50 psi). Replace fuel pump if pressure is low.

4. Inspect Air Intake and Exhaust

Check Air Filter:
- Remove the air filter and inspect for dirt or blockages. Replace if necessary.
Inspect Exhaust System:
- Look for any signs of leaks or restrictions in the exhaust system, including the catalytic converter.

5. Verify Engine Compression

Remove spark plugs and use a compression tester to measure compression in each cylinder.
Compare readings to manufacturer specifications. Address any cylinders with low compression, potentially indicating deeper engine issues.
