I really think there is something wrong here. My car is saying that the o2 heater, secondary air and I think the evap is not ready. Well I had this same problem last year. I haven't disconnected the battery in about 3 months so I don't see why the wouldn't say ready. I've tried doing driving cycles but That doesn't help. So I guess first is there anything wrong with my car? There's no DTC's. I don't have a scan tool or tuning software so I can't verify without going to a shop. Luckly I know the guys and they check the monitors before testing the emissions so it doesn't show that I failed 100 times. Is there a certain driving cycle I should do to try to get just one monitor to say ready? Thanks

I tried that cycle today. Apparently I didn't do it right, I still don't have the monitors ready. If I just let it sit and idle wouldn't test the o2 heater? I let it sit and idle this morning. Then I did the rest of the cycle. I just think my car is screwed up. I'll keep trying.
