Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug socket.
Remove the ignition coil(s) by unscrewing the bolts and gently pulling them off the spark plugs.
Use a spark plug socket to remove each spark plug, inspecting for signs of wear or fouling.
Replace with new spark plugs (gap to manufacturer specifications) and reinstall the ignition coils.

3. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver.
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner into the throttle body and use a soft cloth to wipe away carbon buildup.
Reassemble the air intake duct securely.

4. Check and Replace Fuel Filter (if necessary)

Tools Required: Wrench set, fuel line disconnect tool.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines using the fuel line disconnect tool and remove the fuel filter.
Install a new fuel filter and reconnect the fuel lines.

5. Inspect and Replace Air Filter

Tools Required: None, or screwdriver if necessary.
Open the air filter housing and inspect the air filter for dirt or clogging.
Replace with a new air filter if dirty.
