Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools including an OBD-II scanner, socket set, fuel pressure gauge, and multimeter.

2. Address Ignition System Issues

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the negative battery terminal.
3. Remove spark plug wires or ignition coils.
4. Inspect spark plugs for wear (replace if worn or fouled).
5. Test ignition coils with a multimeter (replace any that are out of spec).

3. Fuel System Inspection

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Start the engine and observe the fuel pressure reading (refer to manufacturer specifications).
3. If pressure is low, inspect the fuel pump and fuel filter for blockages (replace if necessary).

4. Air Intake and Exhaust Examination

Sub-steps:
1. Inspect the air filter and intake hoses for blockages or damage (replace if necessary).
2. Check the exhaust system for leaks, especially around joints and the muffler.
3. Tighten any loose connections and replace damaged sections of the exhaust if needed.

5. Final Checks

Reconnect all components and ensure everything is securely fastened.
Reconnect the negative battery terminal.
Start the engine and listen for abnormal sounds.
