Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Safety glasses and gloves should be worn.

2. Inspect and Replace Fuel Filter

Locate the fuel filter (usually near the fuel tank).
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines from the filter using a fuel line disconnect tool.
Remove the old fuel filter and install the new one, ensuring the flow direction is correct.
Reconnect fuel lines and replace the fuel pump fuse.

3. Clean or Replace Air Filter

Locate the air filter housing.
Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt and debris.
Clean the housing with a soft cloth and install the new air filter.
Reassemble the air filter housing cover.

4. Test and Replace Throttle Position Sensor (if necessary)

Disconnect the electrical connector from the throttle position sensor.
Remove the sensor from the throttle body.
Test the old sensor with a multimeter to check for proper voltage readings.
Install the new throttle position sensor if the old one is faulty.
Reconnect the electrical connector and clear any diagnostic codes.

5. Check and Change Transmission Fluid

Locate the transmission fluid dipstick or drain plug.
Check the fluid level; if low, top off with the manufacturer-recommended fluid.
If the fluid is dark or has a burnt smell, drain and replace it.
Refill the transmission with new fluid, ensuring it is at the correct level.
