Last week I tried to get my car tested for emissions. IN VA, for OBD-II cars they plug it in. My car wasn't ready for the Evap system or the catalyst system and another that I can't recall of the top of my head. I took it to them 3 times, and each time the car 'wasn't ready.' I drove the car 200+ miles, and the last time, I drove it all the way around the Capital Beltway (60+miles), and the car, last time I took it in (last saturday) wasn't ready.
What can cause this? MY understanding is the 3 drive cycles are required typically for the OBD-II self test to be complete. The car has no DTCs.
I had thought the MILs might have caused this, but the O2s seem to be ready according to the inspector.....any input is greatly appreciated.

Maybe this post will help... Description of OBD-II drive cycle And the correct model year document here may help as well... OBD-II Theory and OperationHTH

Ryan,
Do you have a 3L? If you do, I wonder if the PCM flash might not have taken those items into account. Not knowing how the 3L vacuum mods are, I wonder if it is "plugged" or "unplugged" at certain places (causing the evap system not to be recognized).
This will describe the Inspection/Maintenance monitors and the OBD II drive cycle.

And you may just want to scan it first before bringing it in next time.

It is a 3L, but it operates no different than the 2.5L.
I would assume if there was something wrong with the Evap and other systems it would have thrown a MIL by now.....300 miles and no codes so far...
Mark - Thanks for those links; very informative!

It sometimes takes a long time for the monitors to run and complete the drive cycle on some Fords, especially the Contour. You need to drive it until the P1000 code is gone. Also make sure that you don't disconnect the battery cables or interupt the keep alive memory to the PCM until the P1000 code is gone and you get it smogged.

Is the VMV (Vapor Management Valve) hooked up properly? IIRC this component is on located on the firewall kinda near the EVR (EGR Valve Regulator). I don't have experience with the EVAP monitor, but on my Connie the EGR monitor wasn't complete and the CEL also wasn't lit. I ended up replacing the DPFE sensor, doing a UIM/LIM rebuild, and changing the plugs.
If the P1000 I/M Readiness code doesn't go away you'll probably have to investigate the EVAP components to see if you missed something during the 3L install.

Here's a bit more info from The Standard Motor web site.
So what does P1000 mean? A P1000
code means that ALL of the OBD II
monitors have not been completed
since the ECMâ??s memory has been
cleared. It is not necessary to clear
the P1000 code unless you are
performing a state inspection that
requires it to be cleared. This code
could also be the result of the
customerâ??s driving pattern not
permitting all of the OBD II monitors
to complete their drive cycle.
A Ford OBD II drive cycle is a
specific driving pattern which is used
to allow the various OBD II monitors
to run and be completed. The
requirements for the drive cycle to
complete are that all â??Tripâ? monitors
are completed. A trip is defined as an
engine running, vehicle moving, and
the â??Tripâ? monitor has been
completed. Therefore, if all OBD II
trips have been completed, you have
successfully completed the OBD II
drive cycle. All scanners will display
â??Trip Statusâ? as a â??Yesâ? or â??Noâ?. A
â??Yesâ? simply means that a monitor
has run.
Regarding monitors, 1994 & 1995
Ford vehicles use five separate
monitors. 1996 & later vehicles use
as many as nine. Each monitor has
its own criteria to run and complete.
Each monitor is actually a test of a
particular systemâ??s ability to meet
and stay within operating parameters.
When ALL of the monitors have run,
the P1000 code will be erased. It is
best to refer to the specific modelâ??s
manual to determine the exact drive
cycle procedure. When performing a
drive cycle, a smooth, steady foot on
the accelerator will be to your
advantage in completing the cycle.
Abrupt speed changes and erratic
changes in TPS voltage will cause
the ECM to take longer to complete,
and may even abort certain tests.
Avoid wide-open throttle, and
exercise caution while driving and
viewing the scan tool. Most of the
scan tools will indicate each
monitorâ??s status, and whether or not
it has been completed. Some
monitors are run continuously, and as
a result will not indicate a completed
status. If for some reason a â??tripâ? was
not completed during a drive cycle,
the ECM will not need to re-run all of
the monitors. It will begin where it
had left off, so it is not necessary to
repeat the entire process.
With OBD II if you perform a repair
and want to verify that you did repair
the vehicle, you must keep in mind:
the systemâ??s criteria for setting a
code, and whether the ECM is
looking for two consecutive faults. If
this is the case, then itâ??s mandatory
to view the monitorâ??s status and
make sure itâ??s completed. Donâ??t rely
on the MIL light, because it may take
two trips to come on, and that second
trip will be when the customer is
driving the vehicle.

Big Jim points out the exact thing you need to know.
My 'tour took three weeks to run the EVAP monitor. That was with the wife driving it on 80 mile per day round trips.
In regards to the drive cycle, an eight hour shutoff is required to count as a drive cycle (unless overridden).

between 300-550 miles it was finally ready for testing...
