Solution

1. Preparation

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

2. Addressing Fuel System Issues

Check Fuel Pump:
- Use a fuel pressure gauge to measure fuel pressure at the fuel rail.
- If pressure is low, replace the fuel pump.
Inspect Fuel Filter:
- Locate and remove the fuel filter using a socket set.
- Replace it if clogged or according to the maintenance schedule.

3. Ignition System Repair

Replace Spark Plugs:
- Remove the ignition coils using a socket set.
- Replace the spark plugs with OEM parts, torquing to manufacturer specifications (typically around 13-15 lb-ft).
Check Ignition Coils:
- Test each ignition coil with a multimeter for proper resistance.
- Replace any faulty coils.

4. Throttle Body Cleaning

Remove Throttle Body:
- Disconnect the throttle body electrical connector and intake hose.
- Unbolt and remove the throttle body.
Clean Throttle Body:
- Use throttle body cleaner and a soft cloth to remove carbon buildup.
- Reinstall the throttle body, tightening bolts to manufacturer torque specifications.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and check for any warning lights.
