Solution

1. Preparation

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

2. Address Engine Codes

If error codes are present, refer to a service manual for specific fault locations.
Clear the codes after addressing the issues.

3. Air Filter Replacement

Remove the air filter housing cover using a socket set.
Replace the old air filter with a new one, ensuring proper fit.
Reassemble the air filter housing cover and tighten the screws to the manufacturer's specifications.

4. Fuel System Maintenance

If fuel pressure is low, replace the fuel filter if applicable.
Inspect and clean the fuel injectors using a fuel injector cleaning kit, following the kit's instructions for use.

5. Throttle Body Cleaning

Remove the throttle body from the intake manifold using a socket set.
Clean the throttle body using throttle body cleaner and a soft cloth.
Reinstall the throttle body and ensure the gasket is properly seated.

6. Spark Plug Replacement

Remove the ignition coil packs using a socket set.
Replace the old spark plugs with new ones, ensuring they are gapped correctly according to manufacturer's specifications.
Reinstall the ignition coil packs.

7. Battery and Alternator Check

Use a multimeter to test battery voltage (should be around 12.6 volts).
Start the engine and test the alternator output (should be between 13.7 to 14.7 volts).
Replace the battery or alternator if readings are outside the normal range.
