emissions and drive cycle

[lb1159]

Got a 1999 cav. 2.2 that has been sitting for about a year with head gasket blown. Finally got that fixed, and went to get emission tested and rejected because computer shows NOT READY. Since then I have driven over 400 miles, mixed between hi-way and city in 1 week. Heated up and cooled down about 15 times. Cruised on hi-way many times, coasted to stop many times, sat at idle too. Took it back to be tested, and same thing. Not ready on o2 sensor, catalyst, and evap system. the rest passes. Last vehicle I had this driving got the computer to check these systems. Anyone have any suggestions ? Thanks
