Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, multimeter, vacuum gauge, and safety glasses.
Park the vehicle on a level surface and engage the parking brake.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any error codes and diagnose based on manufacturer specifications.

3. Inspect Fuel System

Fuel Pump and Filter
1. Locate the fuel pump (typically in the fuel tank).
2. Disconnect the negative battery terminal for safety.
3. Remove the fuel pump access panel (if applicable) or lower the fuel tank.
4. Inspect the fuel filter for clogs. Replace if necessary.
5. Reinstall the fuel pump and reconnect the battery.

4. Check Ignition System

Spark Plugs and Coils
1. Remove the engine cover if necessary to access spark plugs.
2. Disconnect ignition coils and remove spark plugs using a socket wrench.
3. Inspect spark plugs for wear and carbon buildup; replace if worn.
4. Test ignition coils with a multimeter for proper resistance.
5. Reinstall new or cleaned plugs and reconnect ignition coils.

5. Inspect for Vacuum Leaks

1. Start the engine and allow it to idle.
1. Use a vacuum gauge to check for proper levels.
1. Spray carburetor cleaner around intake hoses and gaskets while the engine is running; listen for RPM changes indicating a leak.
1. Replace any faulty hoses or gaskets.

6. Check Air Filter

1. Locate the air filter housing.
1. Remove the housing cover and take out the air filter.
1. Inspect the filter for dirt and blockage; clean or replace as necessary.
1. Reassemble the air filter housing.
