Need Help with emissions!! I tried to get emissions twice, and both times I failed. I am not throwing any codes, but i am failing on the OBD readyness test. The 2 things that are not ready are my catalyst and Evap. I did have my car retuned..but i put like 600+ miles on it already and it is still "not ready". Does anyone know the drive cycle that i have to do for the catalyst system to "be ready" or what i have to do with a tune to make it ready?? My car is a 02' H/C TA but i do have cats on the car. Kooks LT's and Kooks catted Y. This is just frustrating me cause my tags are expired now and i can't get new ones till i pass this damn thing. Any help will be appreciated. Thanks

I've never had to deal with emissions - is this what you're looking for?

Most people seem to have trouble getting the Evap to ready up. I have deleted my AIR, EGR, and Cats and i tuned out the codes with HP Tuners. Only thing i couldn't get to ready up was Evap. You can have 2 or less unreadies to pass here where i live though. Try drving it around more i guess and do some cold / warm starts. Your catalyst should eventually ready up. Don't know what to tell you about the Evap though.
