Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before starting repairs.

2. Replace Spark Plugs

Remove the engine cover if applicable.
Disconnect the ignition coils from the spark plugs.
Use a spark plug socket and ratchet to remove the old spark plugs.
Check the gap on new spark plugs using a feeler gauge, adjusting as necessary.
Install new spark plugs, tightening them to the manufacturer’s specifications (typically 13-15 lb-ft).
Reconnect the ignition coils.

3. Inspect and Replace Ignition Coils

After removing the spark plugs, inspect the ignition coils for cracks or wear.
Use a multimeter to test the resistance of each coil; replace any that are out of specification.
Install new ignition coils by aligning them with the spark plugs and pressing down firmly until they click into place.

4. Clean or Replace Fuel Injectors

If injectors are clogged, use a fuel injector cleaning kit to flush them.
For severely clogged or damaged injectors, replacement may be necessary.
To replace, detach the fuel rail and carefully remove the injectors; install new ones ensuring proper seating.

5. Check for Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner spray to identify leaks while the engine is running.
Replace any damaged hoses and ensure all connections are secure.
