I have a 2001 Lexus ES300 with 100K miles on it and have the same problem. My trustworthy and honest mechanic cleaned the IAC valve (Idle Air Control) and it is working like a brand new car!!! Good luck!!!

My 2002 Lexus rx300 has check engine light on

Normally you need to connect it to a code reader (scanner) and that should give you the information as a code and direct you to the system in the car that may be causing the light to be on.

If you go to one of your local auto parts stores they will pull up your cars codes for you and tell you what the problem or problems are. Write down the codes and get back to me with the codes. They are usually a P followed by four numbers 0000. This will give me or someone else an idea of what the problem is. Don't panic, it may be something as simple as a loose gas cap. Please let me know what you find out. GOOD LUCK.

I have a 2000 RX 300 and the Engine Check light comes on. When I disconnect the battery it will stay off for a while, but it will eventually come back on. What could be the problem?

If the light came back on after disconnecting the battery, your computer pick up a hard code, means it needs to be check out, autozone came do this for free, get back with us with the code number and we will help you diag. your trouble code.

Engine Light

The check engine light has nothing to do with the oil, water etc. it signals that a fault has occurred in the engines electronic controls and it has failed a test of some system that the cars computer runs every few minutes while the engine is running, it can be one of a 100 different systems that made the light come on, take the car to a Kragen Auto parts store or another chain parts store like it and ask them to run a OBD 2 system test (it's free), this will retrieve the trouble code(s), post the code(s) back on this thread and I will explain what it will take to repair.
