Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Tools required: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, air filter, throttle body cleaner.
Safety warning: Disconnect the battery before working on electrical systems.

2. Addressing Fuel Delivery Issues

Check Fuel Pressure
- Connect the fuel pressure gauge to the fuel rail.
- Turn the ignition key to the "on" position without starting the engine.
- Record the fuel pressure reading; it should be within the manufacturer’s specifications (typically around 50-60 psi).
Replace Fuel Filter if Necessary
- Locate the fuel filter (refer to the vehicle’s service manual).
- Use the socket set to remove the old fuel filter.
- Install the new filter, ensuring proper orientation and secure connections.

3. Cleaning the Throttle Body

Remove the Throttle Body
- Disconnect the negative battery terminal.
- Remove the air intake duct connected to the throttle body.
- Unplug the electrical connector from the throttle body.
- Use a socket set to remove the throttle body mounting bolts and carefully detach it.
Clean the Throttle Body
- Spray throttle body cleaner on a clean cloth or directly onto the throttle body interior.
- Wipe away any carbon build-up, paying attention to the throttle plate and surrounding areas.
Reinstall the Throttle Body
- Reattach the throttle body, tightening bolts to manufacturer's torque specifications.
- Reconnect the electrical connector and air intake duct.

4. Inspect Exhaust System

Check for Blockages
- Visually inspect the exhaust system for any visible signs of damage or blockages.
- If a catalytic converter blockage is suspected, perform a backpressure test to confirm.
