Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during the repair process.

2. Clean or Replace Throttle Body

Clean Throttle Body:
1. Remove the throttle body from the engine using a socket set.
2. Use throttle body cleaner and a soft cloth to clean the interior surfaces.
3. Reinstall the throttle body and reconnect the electrical connectors.
Replace Throttle Body (if necessary):
1. If cleaning does not resolve the issue, replace the throttle body with a new unit.
2. Torque bolts to manufacturer specifications, typically around 12-15 lb-ft.

3. Inspect and Replace Fuel Filter

Locate the fuel filter along the fuel line and check for clogs or damage.
If clogged, replace the fuel filter with a new one.
Ensure all connections are secure and test fuel pressure again.

4. Check Ignition System

Remove spark plugs using a socket set and inspect for wear or deposits.
Replace spark plugs if they show signs of wear or are not within specifications (typically 0.028-0.031 inches gap).
Inspect ignition coils for cracks or damage. Replace any faulty coils.

5. Repair Air Intake System

Inspect the air intake hose for cracks or loose connections.
Replace any damaged hoses or clips.
Ensure the air filter is clean and replace it if necessary.
