 stupid idiot light coming on, fine. But if he goes and shuts it off and restarts it, guess what? Bingo. Yeah, that's normal operation of that system. I'll bet if they put a factory one in, it's going to do the same thing. Because those aftermarket sensors, in fact, a lot of the aftermarket companies make the factory sensors. Bosch, our partner at NGK, NTK, they make a lot of OEM sensors, and they're identical sensors.
