Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Inspect Air Filter

Remove the air filter housing cover.
Take out the air filter and check for dirt or damage.
Replace the air filter if it is dirty or damaged.
Reassemble the air filter housing.

3. Fuel System Check

Inspect fuel lines for any signs of leaks or disconnections.
Check fuel injectors for proper spray pattern by removing them and performing a bench test if necessary.
Replace any faulty fuel injectors or damaged fuel lines.

4. Electrical Connections

Visually inspect all electrical connections that may have been disturbed during servicing.
Reconnect any loose connectors, ensuring they are secure.
Use a multimeter to check for voltage at critical sensors (e.g., MAF, TPS).

5. Battery Inspection

Check battery terminals for corrosion and tightness.
Use a multimeter to measure the battery voltage; it should read around 12.6 volts or higher.
Clean terminals if corrosion is present and tighten connections.
