Alright, So i've failed Emissions about 8 times now due to Readiness not being set. I've driven over 800 miles and have replaced O2 sensors,cleaned MAF sensor,changed spark plugs, the works. The same two monitors have not been set, EVAP and CAT(Catalytic converter). Car is a 2002 toyota celica by the way. Car has a CAI intake, and there is a dent on the intake, but theres no hole at the dent, if that matters. If anyone knows anything about it, any help would be useful,thanks.
