Solution

1. Preparation

Gather tools and parts required.
Disconnect the battery to ensure safety while working on the vehicle.
Allow the engine to cool before proceeding with any repairs.

2. Inspect and Clean the Throttle Body

Remove the throttle body from the intake manifold using a socket set.
Use throttle body cleaner to clean the interior surfaces and the throttle plate.
Reinstall the throttle body and torque to manufacturer specifications (typically around 89 inch-pounds).

3. Fuel System Inspection

Remove the fuel pump fuse and run the engine until it stalls to relieve fuel pressure.
Disconnect the fuel lines and inspect for any leaks or damage.
Replace any faulty fuel lines or components as necessary.
Reconnect the fuel lines and ensure all connections are secure.

4. Spark Plug and Ignition Coil Replacement

Remove the ignition coils by unscrewing them from the cylinder head.
Pull the coils straight out and inspect for damage or wear.
Replace worn spark plugs with OEM parts, ensuring the gap is set to manufacturer specifications.
Reinstall the ignition coils and torque them to the specified value.

5. Fuel Pressure Testing

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine and check the pressure reading.
Compare the pressure to the manufacturer’s specifications (usually around 30-50 psi for most vehicles).
If the pressure is low, consider replacing the fuel pump.
