I had 3 of my lights vsc check engine and one other come on yesterday..the diagnosis from charles barker lexus in v.b. virginia is it needs new throttle body..1387.00 or so but it still drives fine..i had them knock out the warning lights and it seems to still drive o k with no new lights coming on after 100 miles.they say whenever electrical malfuntion exists they replace the whole part...dont know what to do either.
