The Best 1999 Lexus Gs300 Check Engine Light Reset Ideas. Web vsc/vsc off check engine light 99 gs300 vsc/vsc off check engine light on. I took the car to my mechanic who works for toyota for over 20 years;

It could mean a loose gas cap or a more tasking problem like bad spark plugs, bad vvt solenoid, catalytic converter or even transmission. He said it could be the gas tank cover; Is it ok to drive with a check engine light on?
