Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the battery to ensure safety while working.

2. Inspect Fuel System

Check Fuel Pump
- Locate the fuel pump (usually in the fuel tank).
- Use a fuel pressure gauge to test the fuel pressure against specifications (typically 30-50 psi).
- If pressure is low, replace the fuel pump.
Inspect Fuel Filter
- Locate the fuel filter (usually near the fuel tank or along the fuel line).
- Replace the fuel filter if it is clogged or has not been changed according to the maintenance schedule.

3. Examine Ignition System

Check Spark Plugs
- Remove the spark plugs using a socket wrench.
- Inspect for wear or damage; replace if necessary (gap should be set to manufacturer specifications).
Test Ignition Coils
- Disconnect the ignition coils and use a multimeter to check for proper resistance.
- Replace any faulty coils.

4. Inspect Air Intake System

Check the air filter and replace it if it is dirty or clogged.
Inspect the intake manifold for leaks.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and allow it to idle; monitor for stability.
