I have a box stock 15000 miles 04 zo6 ce.Battery went dead before emission test.I charged the battery drove 70 miles mostly expressway ran it through emissions two codes evap,and catalyst not reading.Drove another 90 miles for a total of 160 miles retested still 2 same codes not reading.If it matters it was below 10 degrees today if that matters.My question is how long should it take for the codes to read,is it miles or stop and go?I am driving mostly expressway to put miles on.
