Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug socket.
Remove the engine cover if applicable.
Disconnect the ignition coils and remove them using a socket.
Remove the old spark plugs using a spark plug socket.
Check the gap on the new spark plugs and install them to the manufacturer’s specifications (typically around 0.028 inches).
Reinstall the ignition coils and engine cover.

3. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set.
Locate the transmission fluid dipstick or fill plug.
Check fluid level; if low, add the appropriate transmission fluid (consult the owner’s manual for specifications).
If the fluid is contaminated or burnt, drain the old fluid using a fluid extractor.
Replace the transmission filter if accessible, then refill with new transmission fluid.

4. Inspect and Replace Engine Mounts

Tools Required: Jack, jack stands, socket set.
Raise the vehicle safely using a jack and secure with jack stands.
Inspect the engine mounts for cracks or excessive wear.
Remove bolts securing the damaged mount and replace it with a new mount.
Torque the new mount to the manufacturer’s specifications.

5. Test and Adjust Throttle Position Sensor

Tools Required: Multimeter, screwdriver.
Locate the throttle position sensor on the throttle body.
Disconnect the sensor and check the resistance with a multimeter according to specifications.
If out of range, replace the sensor and reconnect it properly.
