I also took the car to Discount Auto (the only national chain we have in this area) and they said they could only read domestic cars, (Ford Chevy, etc.) no imports like Toyota or Lexus.

The mechanic I took the car to said he could reset the check engine light and then we should wait to see if it comes on again. Two days later it came back on. Later that same day I had to put a tank of gas in the car, and on the way home, the light turned itself off! I am thinking it might have been a gas cap thing. Has anyone else had this smae problem? Also, since the light is out now, I think I should leave the O2 sensors alone, since it seems like there is a pretty high risk in taking them off, such as causing more new problems. Any thoughts?

I found out today that I need to replace the 02 sensors in my 1999 RX300. I've located them online at a fiarly reasonable rate (the mechanic wants $300 each). Is installation something that can be done by someone that does their own basic repairs?
