Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is cool.
Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve any error codes and document them.
Clear the codes and perform a test drive to see if they return.

3. Inspect and Replace Spark Plugs

Remove the engine cover if necessary to access the spark plugs.
Use a socket set to carefully remove each spark plug.
Inspect for wear, carbon buildup, or damage.
Replace with OEM or recommended spark plugs, ensuring to torque them to manufacturer specifications.

4. Check Fuel Delivery System

Use a fuel pressure gauge to test the fuel pressure at the fuel rail.
If pressure is low, check the fuel pump operation and replace if necessary.
Inspect fuel filters for clogs and replace if applicable.

5. Inspect Transmission

Check the transmission fluid level using the dipstick.
If fluid is low or burnt, top off with the appropriate fluid type.
If necessary, flush the transmission system and replace the fluid.
