Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is in gear or park.
Disconnect the battery to prevent electrical shock.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set.
Check fuel pressure:
- Locate the fuel rail and connect the fuel pressure gauge.
- Turn the ignition to the ON position (do not start the engine) and observe the pressure reading; it should meet manufacturer's specifications.
If pressure is low, check the fuel pump, fuel filter, and fuel lines for blockages or failure.
Replace any faulty components as necessary.

3. Ignition System Check

Tools Required: Spark plug socket, multimeter.
Remove spark plugs and inspect for wear or deposits.
Check ignition coils with a multimeter to ensure they are within spec.
Replace any damaged or worn spark plugs and coils.

4. Vacuum Leak Inspection

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner to find leaks: spray around the intake manifold and vacuum lines while the engine is running; listen for changes in engine RPM.
Replace any damaged hoses or gaskets.

5. MAF Sensor and Throttle Body Cleaning

Tools Required: MAF cleaner, throttle body cleaner, soft cloth.
Disconnect the MAF sensor connector and remove the sensor.
Clean the MAF sensor with MAF cleaner and let it dry completely before reinstalling.
Remove the throttle body and clean it with throttle body cleaner to remove carbon buildup.

6. Reconnect and Test

Reconnect the battery and all connectors.
Start the engine and monitor for stability at idle and during acceleration.
