yes, they can pass any car, with OBD2, in many states, with CEL out, and scans clear and all monitors run out (1 can be late)
then the gas cap seal is tested, (leak down test)
420s means only lazy cat, and is not going to fail or cause issues. in fact, it might get better the more you drive.
if no feds biting at heals. 420s is no problem..... in 1995 there was no 420s. and the engine ran perfectly.
if the car runs great, good mpg, no misfire, bogging or overheating (its in closed loop, so all is good)
its ready to go.
HAVE FUN !!!!!
i just keep faith on 420s, it can cure itself..
i dont think the non TWC cat (if that is what it is) can do this. three way cat. ive seen 2way cats pass 420s. (a great topic in own rights)
