Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge, cleaning supplies.
Ensure the vehicle is parked on a level surface and securely positioned with the parking brake engaged.

2. Addressing Air and Fuel Supply Issues

a. Replace Air Filter

Locate the air filter housing.
Remove the clips or screws securing the housing.
Take out the old air filter and replace it with a new one.
Reassemble the housing, ensuring it is securely fastened.

b. Inspect and Replace Fuel Filter (if applicable)

Locate the fuel filter, typically along the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines (use a line disconnect tool if necessary).
Replace the old filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and reinstall the fuse.

3. Spark Plug Inspection and Replacement

Remove the ignition coil cover (if applicable).
Disconnect the ignition coils and remove them using a socket set.
Take out the old spark plugs using a spark plug socket.
Check the gap on new spark plugs and install them, ensuring they are torqued to manufacturer specifications.
Reinstall ignition coils and cover.

4. Throttle Body Cleaning

Disconnect the battery to avoid electrical issues.
Remove the intake duct connected to the throttle body.
Spray throttle body cleaner into the throttle body and wipe clean with a lint-free cloth.
Reassemble the intake duct and reconnect the battery.

5. Transmission Fluid Check and Replacement

Check fluid level through the dipstick. Add fluid if low.
If fluid is dark or burnt, consider a transmission fluid change.
For fluid change: Remove the transmission pan, replace the filter, and refill with new fluid according to manufacturer specifications.
