Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical shorts.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve and document any error codes displayed.
Research codes to identify specific issues related to the engine.

3. Inspect and Replace Components

A. Engine Oil

Remove the oil dipstick and check oil level and condition.
If low or dirty, drain the old oil and replace with manufacturer-recommended oil.
Refill to the appropriate level.

B. Air Filter

Open the air filter compartment and remove the old air filter.
Inspect for dirt and blockages.
Install a new air filter if necessary, ensuring proper fit.

C. Spark Plugs

Remove the spark plug wires and unscrew the spark plugs using a socket.
Inspect for wear and deposits; replace if damaged or worn beyond limits.
Torque new spark plugs to the manufacturer's specifications.

D. Fuel Pump Pressure

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine and check the pressure.
If pressure is below specifications, replace the fuel pump.

4. Reconnect and Test

Reconnect the battery and start the engine.
Allow the engine to idle and monitor for any warning lights.
Test drive the vehicle to ensure all systems function correctly.
