Lexus Repair: Lexus 2000 RX 300, rx 300, warning light

Question
While accelerating up a hill my car lost power and started to idle very rough and loud and shortly after my check engine light came on.  Prior to this I did not have a warning light of any kind that there was a problem. I immediately parked the car and hesitate to drive it even though it does still run. Can you give me any idea as to what has happened and can driving it to a garage cause more damage. I have never had any problem with the car.  Thanks. Mary  

Answer
Hello Mary, I would not drive it unless you have no other choice. What needs to happen is the engine code needs to be extracted and from there they should have a good idea whats going on. It may be a coil not giving spark to one of the cylinders. Remember, use the dealer or a shop that has had someone trained by Lexus. You will have less problems and less expense this way.
