Hey, I just joined the site. I have a 93 SC400 with about 115,000 miles. I took it to a reputable Lexus Dealership, Henessey in ATL, to get rid of trac and check engine lights. They wanted to charge me $350 for an o2 sensor, but I refused because inspection is not for another year (hope I'm not harming the envrnmt too much). Anyway those lights have remained on for about 2 months and the car runs fine. I was wondering if my trac light is on permanently, does my trac system not work in rainy weather for example? Is it a serious problem to not have both engine and trac lights on, and do I need an o2 sensor?
The car also makes some scrathing noises when turning, maybe its just the age.
Also, how many miles can the sc rack up before it fails.
I really appreciate the feedback.
