I have heard of several people here in AZ who simply had to pass the OBD2 test, with no visual test. However, I have a buddy with a 2001 Firebird Trans Am who had to do the rollers and a sniff test! This car is also OBD2 compliant, so I don't know why they made him jump through hoops (and his car is bone stock!).

I get tested for the first time in Feb. so I'm going to throw my cats back on just to cover the bases.
As for your buddy's Firebird, I don't know how to explain that one.

I have an 03 model, but i don't think i am scheduled to get tested until 08 or 09 in CA. Is it different in AZ?

How about NJ? I think if its OBD2 all they do is scan the car. I had my 2003 inspected but I was not watching what they did. I am pretty sure it is non rollers. Now for my 87 300zxt they put it on the rollers.

+1 on AZ just looking for ECU codes on modern cars.
lol at what the smog people would be thinking seeing/hearing a highly modified car pull in and pass with an ECU read.
Now when I'd go to pass my 78 vette, they did everything - checked for cats, popped the hood, sniffer test, etc etc...
well good luck...the code will probably come back pretty quick anyway.
I think I've heard the ECU can store some codes long term that the OBDII test looks for that simply erasing the short term code won't fix
