I have a 99 Ford Taurus that won't pass AZ State required emissions test. I have tried the drive cycle in the owners manual and it still wouldn't pass emissions. They said the drive cycle wasn't complete. I went online to find the definitive way to complete the drive cycle. What I have learned is you need a scan tool. My question is this, "Can I complete a Drive Cycle with out using a scan tool? Pleeeease Help!

a drive cycle is not measured in miles driven but in the type of driving done, here is a ford drive cycle procedure to clear the not ready code.
Ford Motor Company Driving Cycle
Description of OBDII Drive Cycle
The following procedure is designed to execute and complete the OBDII monitors and to clear the Ford P1000, I/M readiness code. To complete a specific monitor for repair verification, follow steps 1 through 4, then continue with the step described by the appropriate monitor found under the "OBDII Monitor Exercised" column. When the ambient air temperature is outside 4.4 to 37.8°C (40 to 100° F), or the altitude is above 2438 meters (8000 feet), the EVAP monitor will not run. If the P1000 code must be cleared in these conditions, the PCM must detect them once (twice on some applications) before the EVAP monitor can be "bypassed" and the P1000 cleared. The Evap "bypassing" procedure is described in the following drive cycle.
The OBDII Drive Cycle will be performed using a scan tool. Consult the instruction manual for each described function. NOTE: A detailed description of a Powertrain Control Module (PCM) Reset is found in this section, refer to the table of contents.

Some times it takes several days to reset the drive-cycle = Starting from cold state, different speeds for a certian distance, EVAP from cold condition and time. If the PCM dosen't get the proper readings from the sensors it won't reset untill it does. If you keep getting an " incomplete" on a system, then there's a problem with that system and you will have to find and repair it.
Give it a few days of running varried trips.
