I think i heard 100 miles but i don't know first hand. DId you reset your cpu

also, before the test you should drive around for 20 minutes on the highway to warm up the cats before the test. and leave your car running while you wait for your turn.

but if you're throwing codes, I dunno what to do

I thought that to clear a code, the car has to be driven at least 3 times for like 15 minutes or more each time, with cool down time between each run? Or something like that.

i guess the smog machine was picking up my old codes even after it got restarted
