Replaced Cat, cannot get I/M ready ??
 

So I finally replaced the CAT on my Van I was only getting the P0420 code and could not find anything else wrong with the Vehicle, Now I cannot remember what I need to do to get the I/M ready so I can go to DEQ to get new tags.
I changed the CAT on Thursday 9-26-13 Have drove it to the store 4 times, drove it down the freeway (at 60 MPH for about 5 Miles One way then back 10 Miles total) Drove it around town just to try to get the I/M ready and still I get nothing, have not gotten the MIL light but cannot get it to be ready for the DEQ test.
What am I missing here? I cannot find the info on here nor in my service manual and it is driving me Batty, I need to take it in within the next 3 hours or I will be driving on expired, Oooops I am on expired tags as I speak.
