Solution

1. Preparation

Gather tools and parts; ensure vehicle is parked on a level surface.
Disconnect the negative battery cable to avoid electrical shocks.
Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, throttle body cleaner.

2. Address Fuel System Issues

2.1. Fuel Pump Test

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position without starting the engine to check pressure.
Ensure pressure meets the specifications (typically around 50-60 psi).
If pressure is low, replace the fuel pump.

2.2. Fuel Filter Replacement

Locate and remove the fuel filter using a socket set.
Replace with a new fuel filter, ensuring correct orientation and tight connections.

3. Inspect and Replace Ignition Components

3.1. Spark Plug and Ignition Coil Inspection

Remove the ignition coils using the socket set.
Inspect spark plugs for wear or deposits; replace if necessary.
Replace ignition coils if they show signs of damage or wear.

4. Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
Wipe clean with a lint-free cloth to remove carbon buildup.

5. Reassemble and Final Checks

Reconnect all components removed during the repair.
Reconnect the negative battery cable.
Clear any error codes using the OBD-II scanner.
