Solution

1. Preparation

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

2. Inspect Fuel System

Fuel Pump:
- Locate the fuel pump access panel (if available) or remove the rear seat to access the pump.
- Disconnect the electrical connector and fuel lines from the pump.
- Replace the fuel pump if it is faulty or not delivering the correct pressure (typically between 50-60 psi for most BMW engines).
Fuel Filter:
- Locate the fuel filter and disconnect the fuel lines.
- Replace the fuel filter if it is clogged or contaminated.

3. Check Air Intake and Throttle

Air Filter:
- Remove the air intake duct and inspect the air filter for dirt and debris.
- Replace the air filter if it is dirty.
Throttle Body:
- Disconnect the intake duct from the throttle body.
- Clean the throttle body using throttle body cleaner and a soft cloth to remove carbon buildup.

4. Inspect Ignition System

Spark Plugs:
- Remove the spark plug wires and use a spark plug socket to remove the spark plugs.
- Inspect for wear or fouling and replace them if necessary (use OEM specifications for gap size).
Ignition Coils:
- Check each ignition coil for signs of damage or corrosion.
- Replace any faulty ignition coils.

5. Reassemble and Test

Reconnect all components in reverse order of disassembly.
Reconnect the battery and clear any diagnostic trouble codes using the OBD-II scanner.
Start the engine and allow it to idle to check for any abnormalities.
