Readiness test for Emissions

[imari]

Hey guys,
I have a 01 Boxster and had a CEL on so I got the repair done (air pump and then they unclogged some sort of valve or hoses). The CEL light went off but I've been driving the car to get it set to pass the emissions test. I've tried twice so far (after driving over 150 miles) but it's STILL no passing the "readiness" test. Does anyone know how long/far I have to drive it before it's ready to pass emissions?????

Any advice is greatly appreciated. Thanks!
