Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, throttle body cleaner.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts during repairs.

2. Clean the Throttle Body

Remove the air intake duct by loosening the clamps and disconnecting any sensors.
Access the throttle body by unbolting it from the intake manifold (use a torque wrench to note the original torque values for reinstallation).
Spray throttle body cleaner inside the throttle body and use a clean rag to wipe away carbon deposits.
Reassemble by reversing the disassembly steps, ensuring all connections are secure.

3. Inspect and Replace Spark Plugs

Remove the ignition coil cover by unbolting it (if applicable).
Disconnect the ignition coils and remove them using a socket set.
Unscrew the spark plugs using a spark plug socket and inspect them for wear or fouling.
Replace with new spark plugs, ensuring to gap them according to manufacturer specifications.
Reinstall the ignition coils and cover, ensuring all bolts are torqued to specifications.

4. Test and Replace Fuel Filter (if necessary)

Locate the fuel filter and check for any signs of blockage or leaks.
If the filter is clogged, relieve fuel pressure from the system, and disconnect the fuel lines.
Replace the old filter with a new one, ensuring proper orientation and secure connections.
Reconnect the battery terminal and turn the ignition to the "ON" position to prime the fuel system before starting the engine.
