Often caused by a loose gas cap or fouled or failed air fuel O2 sensor. Check your gas cap is fully ratcheted, Drive a day or two. If lights don't clear you will need a code reader attached to the car to diagnose.

you need a new cd changer, or a used one. Id just get an aftermarket one and have no more problems.

the coolant needs to be serviced @ 60k according to lexus reccomendation. theres a timing belt that needs to be changed @ 90k miles. I usually just change the coolant with the timing belt because you have to take the water pump off anyway and replace the engine coolant.
