Solution

1. Preparation

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

2. Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to remove carbon buildup.
Reinstall the air intake duct ensuring all clamps are secure.

3. Replace the Air Filter

Locate the air filter housing and open it according to the manufacturer's instructions.
Remove the old air filter and replace it with a new one, ensuring it fits snugly.
Close the air filter housing securely.

4. Check and Replace Spark Plugs (if necessary)

Remove the ignition coil cover if applicable.
Disconnect the ignition coils from the spark plugs.
Use a spark plug socket to remove old spark plugs.
Inspect the old plugs for wear; replace with new plugs if necessary, torquing to manufacturer specifications.

5. Fuel Pressure Test and Repair

Connect a fuel pressure gauge to the fuel rail.
Start the engine and observe the fuel pressure reading, ensuring it meets manufacturer specifications.
If pressure is low, check for clogged fuel filters or weak fuel pumps and replace as needed.
