Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to ensure safety before beginning any electrical work.
Raise the vehicle securely on jack stands if undercarriage inspection is required.

2. Throttle Body Cleaning

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reinstall the air intake duct ensuring all connections are secure.

3. Fuel System Inspection

Remove the fuel pump relay from the fuse box.
Connect the fuel pressure gauge to the fuel rail.
Reinstall the relay and turn the ignition on (do not start) to check the fuel pressure reading; it should match manufacturer specifications (usually between 40-50 PSI).
If pressure is low, replace the fuel filter or fuel pump as necessary.

4. Ignition System Service

Remove spark plugs and inspect for wear, carbon deposits, or damage.
Replace any faulty spark plugs with OEM equivalents and ensure proper gap settings.
Check ignition coils for proper resistance using a multimeter; replace if out of spec.

5. Exhaust System Inspection

Visually check the exhaust system for any signs of blockage or damage.
If the catalytic converter is suspected to be clogged, conduct a back pressure test.
Replace the catalytic converter if it fails the back pressure test.
