Solution

1. Preparation

Gather tools and parts required for repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Air Intake Issues

Tools Required: Socket set, screwdrivers.
Inspect the air filter and replace it if clogged.
Check the intake hoses for leaks and replace any damaged sections.

3. Inspect and Repair Fuel System

Tools Required: Fuel pressure gauge, wrench set.
Connect the fuel pressure gauge to the fuel rail and check the pressure against specifications.
If pressure is low, replace the fuel filter and inspect the fuel pump for operation.

4. Examine the Exhaust System

Tools Required: Jack and jack stands, socket set.
Raise the vehicle and inspect the exhaust system for any visible blockages or damage.
If the catalytic converter is found to be clogged, replace it with a new unit.

5. Test and Replace Ignition Components

Tools Required: Multimeter, spark plug socket.
Remove and inspect spark plugs for wear, replacing them if necessary.
Test the ignition coils for voltage output; replace any faulty coils.
