Did you reset your computer right before going in?
You need to drive it around for a while. I think in Texas we are allowed up to 2 not ready systems, or something like that.

his car's an 01... at least here in IL you're only allowed 1 not ready for 01+, 00 or previous you're allowed 2
Sounds like you just reset the PCM? (either manually, or battery went dead, replaced battery , etc..)

It's pointless to reset the ecm/pcm ... cause that resets ALL readiness tests....
I'm emissions legal and I did 5 cold starts (to operating temp), several warm starts (let car run for a few minutes on starting... to switch to closed loop) and about 25 miles or so driving .... only had 1 readiness test not complete (evap)
