Hi;
I bought the headers for my '07 IS250 and install it, when I finished the installation of it there was any problem on the Check VSC light of the car, but at the next 2 days the light came on, I use a OBDII and clean the error code, but then again anytime I accelerate through the 6K rpm's the light came up again. I know for other cars their is a O2 sensor that can replace it and turn the light off but I don't know if it can work on the IS250 if somebody knows something please let me know.
