what is the difference between the orange engine light ant the red 1

orange is the check engine light. have it checked at a shop for bid. Roy

A Check Engine Light on a ES300 if you don't notice the engine running rough is usually a evaporative emission issue or a heater circuit in one of the Oxygen sensors, not vitally serious but best to get it checked out. A Check Engine Light that flashes constantly means damage is being done to the catalytic converter and it is best to shut off the engine.
