Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set, safety glasses.
Sub-steps:
1. Locate the fuel rail and attach the fuel pressure gauge to the Schrader valve.
2. Turn the ignition key to the "On" position (do not start the engine) and check the fuel pressure reading; it should be within the manufacturer's specifications.
3. If pressure is low, inspect the fuel pump and replace if necessary.

3. Ignition System Check

Tools Required: Spark plug socket, multimeter.
Sub-steps:
1. Remove the spark plugs using a spark plug socket.
2. Inspect each spark plug for wear or damage; replace if necessary.
3. Use a multimeter to test the ignition coils for proper resistance; replace any faulty coils.

4. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft brush, clean rags.
Sub-steps:
1. Disconnect the throttle body from the intake manifold by removing the mounting bolts.
2. Spray throttle body cleaner into the throttle body and use a soft brush to scrub away carbon deposits.
3. Wipe clean with a rag and reassemble the throttle body to the intake manifold.

5. Vacuum Leak Inspection

Tools Required: Smoke machine or carburetor cleaner.
Sub-steps:
1. With the engine running, use a smoke machine to check for vacuum leaks around the intake manifold.
2. Alternatively, spray carburetor cleaner around the manifold and listen for RPM changes.
3. Repair or replace any damaged hoses or gaskets found during the inspection.
