Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, cleaning cloth, socket set.
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
Wipe clean with a cloth, ensuring all carbon deposits are removed.
Reattach the air intake duct securely.

3. Check and Replace Transmission Fluid (if necessary)

Tools Required: Transmission fluid, funnel, socket set.
Locate the transmission dipstick and check the fluid level.
If the fluid is low or burnt, drain the old fluid and refill with the manufacturer-recommended fluid.
Ensure to torque the transmission pan bolts to the manufacturer's specifications.

4. Fuel Pump Pressure Test

Tools Required: Fuel pressure gauge, hose clamps.
Locate the fuel pressure test port on the fuel rail.
Connect the fuel pressure gauge and turn the ignition to the 'ON' position without starting the engine.
Check the pressure reading against the manufacturer's specifications. If low, consider replacing the fuel pump.

5. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench.
Remove the spark plug wires carefully.
Use a spark plug socket to remove the spark plugs.
Inspect for wear or fouling; replace with OEM or equivalent spark plugs.
Torque the new spark plugs to the manufacturer's specifications before reattaching the wires.
