Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, vacuum gauge.
Allow the engine to cool down before starting any work. Disconnect the battery to prevent electrical shorts.

2. Address Ignition System Issues

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Inspect the spark plugs for wear or carbon buildup; replace them if necessary with OEM parts.
3. Test the ignition coils using a multimeter for proper resistance; replace any faulty coils.

3. Inspect Fuel System

Sub-steps:
1. Check the fuel pressure using a fuel pressure gauge to ensure it meets manufacturer specifications.
2. Remove and clean the fuel injectors using a cleaning kit or replace them if they are clogged.
3. Inspect the fuel filter and replace it if it is clogged or hasn’t been replaced per maintenance schedule.

4. Check for Vacuum Leaks

Sub-steps:
1. Use a vacuum gauge to check for proper manifold vacuum readings.
2. Inspect all vacuum hoses for cracks or disconnections; replace as necessary.
3. Test the intake manifold gasket for leaks using a smoke machine or carburetor cleaner spray.

5. Inspect Exhaust System

Sub-steps:
1. Visually inspect the exhaust system for any signs of damage or blockages.
2. Check the catalytic converter for signs of overheating or clogging.
3. If necessary, remove and replace the catalytic converter using proper torque specifications for all bolts.
