Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts during the repair.

2. Inspect and Replace Fuel Filter (if necessary)

Locate the fuel filter (usually along the fuel line).
Use a fuel line disconnect tool to relieve pressure and disconnect the fuel lines.
Remove the fuel filter from its mounting bracket.
Install the new fuel filter, ensuring the flow direction is correct.
Reconnect the fuel lines and check for leaks before reattaching the battery.

3. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body to remove carbon buildup.
Move the throttle plate manually to clean behind it.
Reassemble the air intake duct and reconnect the battery.

4. Replace Spark Plugs and Ignition Coils (if faulty)

Remove the engine cover to access the ignition coils.
Disconnect the wiring harness from each ignition coil.
Remove the bolts securing the ignition coils and take them out.
Replace with new ignition coils and spark plugs, ensuring correct torque specifications for installation.
Reconnect the wiring harness and engine cover.

5. Inspect for Vacuum Leaks

Visually check all hoses connected to the intake manifold for cracks or disconnections.
Use a smoke machine or carburetor cleaner to detect any leaks while the engine is running.
Repair or replace any damaged hoses and recheck for leaks.
