Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, throttle body cleaner.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before servicing.

2. Addressing Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any error codes.
Clear the codes and test drive to see if they reappear.

3. Inspect Air Filter

Locate the air filter housing and open it.
Remove the air filter and inspect it for dirt and debris.
Replace the air filter if it is clogged.

4. Test Fuel Pressure

Attach the fuel pressure gauge to the fuel rail.
Turn the ignition on (do not start the engine) and check the fuel pressure reading.
If the pressure is below specifications, replace the fuel pump.

5. Clean Throttle Body

Remove the throttle body from the intake manifold.
Use throttle body cleaner and a soft cloth to clean the interior surfaces.
Reinstall the throttle body and ensure all connections are secure.

6. Inspect Ignition Components

Remove the spark plugs and inspect them for wear or deposits.
Replace worn spark plugs with OEM specifications.
Check ignition coils for proper operation using a multimeter and replace if faulty.

7. Check Transmission Fluid

Locate the transmission dipstick and remove it.
Check the fluid level and condition (look for discoloration or burnt smell).
If necessary, drain and replace the transmission fluid according to manufacturer specifications.
