Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to ensure safety while working.
Allow the engine to cool before starting repairs.

2. Replace Spark Plugs (if faulty)

Remove the engine cover if necessary using a socket set.
Disconnect each ignition coil by unclipping the connector.
Unscrew the spark plugs using a spark plug socket and ratchet.
Inspect and replace with new spark plugs according to manufacturer specifications.
- Torque new spark plugs to 15-20 lb-ft.
Reconnect ignition coils and secure the engine cover.

3. Clean or Replace Fuel Injectors

Remove the fuel rail by unscrewing the retaining bolts and disconnecting fuel lines (use caution as fuel may spill).
Inspect injectors for any clogs; clean with a fuel injector cleaner or replace if necessary.
Reinstall the fuel rail and ensure all connections are secure.

4. Check and Replace Transmission Fluid (if necessary)

Locate the transmission dipstick and check the fluid level.
If low or burnt, drain the old fluid using a fluid pump.
Replace with the manufacturer-recommended transmission fluid.
- Fill until the correct level is reached as per the dipstick markings.

5. Inspect and Test Throttle Position Sensor

Locate the throttle body and disconnect the TPS connector.
Use a multimeter to check the resistance across the sensor terminals; it should vary smoothly as the throttle is opened and closed.
Replace the TPS if it shows erratic readings or is outside of manufacturer specifications.
