Car companys need to fix this crap... my dad has a Toyota, and he can't get it inspected until its fixed. He's been going at it for weeks, now inspection is up he still needs to drive it just to see if it the light will come back on... anyways, more of a rant then a solution, but good luck!
I FULLY understand your rant... I think there is a dollar limit that once you spend this amount on emission, they have to pass your car... I think the amount is $200, but this may have changed or may differ from state to state.... I hope your Dad gets his car fixed.

'rboverman' is on the right track. If you don't have any codes but all monitors are not in the ready state it's just a matter of putting the car under certain load conditions during a 'drive cycle' to set them. Sometimes it will take more then one cycle, but all monitors should go to the ready state.

Edit: Temperature shouldn't prevent ready state. The PCM should compensate for that.

I have a DHP PowrTuner and I saw a setting in the PCM for what temp to start the catalyst test, so I can adjust it (but I'd rather not, as there is a reason GM decided on 40 degrees and I don't know what it was to mess with it).
Again, this is an '04 Grand Am. Some of this information can vary between different cars.
