Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Disconnect the battery to prevent electrical issues while working on the vehicle.
Gather necessary tools and parts.

2. Inspect and Clean Throttle Body

Remove the engine cover and disconnect the intake duct from the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle body.
Reattach the intake duct and secure all connections.

3. Check Fuel Delivery System

Locate the fuel pump access panel (if applicable) or remove the rear seat to access the fuel pump.
Test the fuel pump operation using a multimeter or fuel pressure gauge, ensuring it meets manufacturer specifications.
Replace the fuel filter if clogged or if it exceeds recommended service intervals.

4. Examine Ignition System

Remove spark plugs and inspect them for wear or deposits.
Replace spark plugs if necessary, ensuring they are gapped correctly.
Check ignition coils for proper operation using a multimeter, replacing any faulty coils.

5. Inspect for Vacuum Leaks

Visually inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
Use a smoke machine or carburetor cleaner to detect leaks while the engine is idling.
Replace any damaged hoses or gaskets as required.
