Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety during the repair process.

2. Address Ignition System

Sub-steps:
1. Remove the engine cover if equipped to access the ignition coils.
2. Disconnect the electrical connectors from the ignition coils.
3. Remove the bolts securing the ignition coils and take them out.
4. Inspect and replace any faulty spark plugs (use OEM specifications for gap and type).
5. Reinstall the ignition coils and reconnect the electrical connectors.

3. Inspect Fuel System

Sub-steps:
1. Locate and remove the fuel injector rail.
2. Check each injector for signs of blockage or leaks.
3. Clean or replace any clogged fuel injectors, ensuring proper seating when reinstalling.
4. Reattach the fuel rail and ensure it is properly tightened to manufacturer specifications.

4. Check for Vacuum Leaks

Sub-steps:
1. Inspect all visible vacuum hoses for cracks or disconnections.
2. Use a vacuum gauge to test the intake manifold for leaks.
3. Replace any damaged hoses and reseal any leaking connections.

5. Verify Engine Compression

Sub-steps:
1. Remove spark plugs to access cylinder heads.
2. Attach a compression tester to each cylinder.
3. Crank the engine and record the compression readings.
4. Compare results to the manufacturer's specifications; replace worn components if necessary.
