Solution

1. Preparation

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

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set.
Check fuel pressure at the fuel rail using the fuel pressure gauge.
- Connect the gauge to the fuel rail service port.
- Turn the ignition on without starting the engine and record the pressure reading.
- Compare the reading to manufacturer specifications.
If pressure is low, inspect the fuel pump and fuel filter for clogs or failures.

3. Air Intake System Inspection

Tools Required: Screwdriver set, vacuum gauge.
Remove the air intake duct from the throttle body.
Inspect the air filter for dirt and clogs; replace if necessary.
Check for vacuum leaks by using a vacuum gauge on the intake manifold.

4. Ignition System Replacement

Tools Required: Socket set, torque wrench.
Remove the ignition coil(s) by disconnecting the electrical connectors and unscrewing them.
Replace any faulty ignition coils with new ones.
Replace spark plugs if they show signs of wear or fouling.
- Use a torque wrench to tighten spark plugs to manufacturer specifications.

5. Reassemble and Reconnect

Reinstall all components removed during inspection.
Reconnect the battery and ensure all connections are secure.
Start the engine and let it idle to check for any issues.
