Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off and cool.
Disconnect the battery to prevent any electrical shorts during the repair.

2. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdrivers.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
Wipe away carbon buildup with a soft cloth.
Reattach the air intake duct securely.

3. Inspect and Replace Air Filter

Tools Required: Screwdriver or ratchet set (if required for air box cover).
Remove the engine cover if necessary to access the air filter.
Take out the air filter and check for dirt and debris.
Replace with a new air filter if it is dirty or obstructed.
Reassemble any components that were removed.

4. Test Fuel Pressure

Tools Required: Fuel pressure gauge.
Locate the fuel pressure test port on the fuel rail.
Connect the fuel pressure gauge and turn the ignition key to the "ON" position without starting the engine.
Check if the fuel pressure reaches the manufacturer's specifications (usually around 40-50 psi).
If pressure is inadequate, replace the fuel pump or fuel filter as necessary.

5. Inspect and Replace Ignition Components

Tools Required: Socket set, torque wrench.
Remove the ignition coils and inspect spark plugs for wear or deposits.
Replace worn spark plugs with OEM parts and reassemble the ignition system.
Ensure all connections are tight and secure.
