Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Inspect Fuel System

Tools Required: Fuel pressure gauge, screwdriver set, safety glasses
Remove the fuel pump relay from the fuse box.
Connect the fuel pressure gauge to the fuel rail service port.
Turn the ignition to the "ON" position (without starting the engine) to check fuel pressure; it should be within the manufacturer's specifications (typically 40-50 psi).
If pressure is low, inspect and replace the fuel pump if necessary.

3. Inspect Ignition System

Tools Required: Spark plug socket, multimeter
Remove the spark plugs and inspect for wear, carbon buildup, or damage. Replace if necessary.
Use a multimeter to test the ignition coils for proper resistance. Replace any faulty coils.
Reinstall spark plugs and ensure they are torqued to the manufacturer's specifications (usually around 13-16 lb-ft).

4. Check for Vacuum Leaks

Tools Required: Smoke machine or carburetor cleaner
With the engine running, use a smoke machine to detect leaks in the intake manifold and vacuum hoses. Alternatively, spray carburetor cleaner around suspected areas; if the engine idle changes, a vacuum leak is present.
Replace any damaged hoses or gaskets found during this inspection.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and let it idle for a few minutes to check for stability.
Monitor for any new error codes or warning lights.
