Solution

1. Preparation

Gather required tools and parts for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Inspect the air filter; if dirty or damaged, replace it with a new one.
Reassemble the air filter housing cover securely.

3. Fuel System Inspection

Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Connect the fuel pressure gauge to the fuel rail and check pressure specifications (should be around 50-60 psi for BMW X5).
If pressure is low, inspect the fuel pump and fuel filter; replace if necessary.

4. Throttle Body Cleaning

Remove the throttle body by disconnecting the electrical connector and unscrewing the mounting bolts.
Clean the throttle body with throttle body cleaner and a soft cloth, ensuring no residue remains.
Reinstall the throttle body, ensuring all connections are secure.

5. Spark Plug and Ignition Coil Inspection

Remove the ignition coil covers using a socket set.
Inspect the spark plugs for wear; replace if they have excessive wear or deposits.
Test ignition coils with a multimeter, replacing any faulty units.

6. Exhaust System Check

Inspect the exhaust system visually for any signs of damage or blockage.
If any obstructions are found, repair or replace the affected components.
