Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to avoid electrical shocks.

2. Clean Throttle Body

Remove the air intake duct attached to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body while opening the throttle plate with your hand.
Wipe clean with a lint-free cloth to remove carbon deposits.

3. Inspect Fuel System

Reconnect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading; it should match the specifications in the service manual (typically around 40-50 psi).
If pressure is low, check the fuel pump and fuel filter for issues.
Replace the fuel filter if it is clogged.

4. Check Ignition System

Remove spark plugs using a socket wrench.
Inspect spark plugs for wear; replace if they are worn or fouled.
Test each ignition coil with a multimeter; replace any faulty coils.

5. Inspect Exhaust System

Visually inspect the exhaust system for any visible damage or blockages.
If a blockage is suspected, remove the catalytic converter and check for clogs by looking through it.
If clogged, replace the catalytic converter.
