Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool down before beginning the work.

2. Inspect and Replace Ignition Components

Tools Required: Socket set, torque wrench, ignition coil puller.
Remove the engine cover if necessary.
Disconnect the electrical connectors from the ignition coils.
Unbolt the ignition coils and remove them from the spark plugs.
Inspect spark plugs for wear and replace if necessary (gap to manufacturer specifications).
Install new ignition coils, ensuring they are properly seated and connectors are reattached.
Torque bolts to manufacturer specifications.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge, multimeter.
Locate the fuel pump relay and test for proper operation using a multimeter.
If necessary, replace the fuel pump relay.
Connect the fuel pressure gauge to the fuel line and turn the ignition on (do not start).
Check the pressure reading against manufacturer specifications; if low, consider replacing the fuel pump.
Inspect and replace fuel filter if clogged.

4. Check for Vacuum Leaks

Visually inspect all hoses connected to the intake manifold for cracks or disconnections.
Use a smoke machine or carb cleaner to identify leaks.
Replace any damaged hoses and ensure all connections are secure.
