Re-set OBD II protocol after dead battery, or??
I have had two dead battery incidents in the past 6 months...same battery. I am putting it on a Battery Tender...learned my lesson. In addition, the motor got really wet in a down pour while spending a night at the track. The following day, it misfired like a ****....I let it idle for about an hour but the damn CEL was on.
Had it reset...then the second dead battery incident...just too much for the OBD II. It is not "electronically" ready for its smog test. I have to take it out and drive it using the EPA URBAN DYNOMETER DRIVING DRIVING SCHEDULE, and do it 2X...what a PITA.
I'll post up the results...hopefully I can pass smog! The pdf is too big to wost...so if you want it, send me a PM

Yes, any time you reset, or loose power the "readiness" codes are not set. The only way to get them to pass/fail is to drive the car.
You may want to check your plug wires & or cap & rotor. Usually when you have water related misfires, it's cuz you need to do a tune up on the ignition parts.
Is it really BAD that you got to drive the car?

Martin,
I didn't have any luck with the OBD cycle reset while driving on the street. I made it easy on myself called the State and set up an appointment with a state appointed refree station, in order to get an appointment I had to tell them that I couldn't pass SMOG because the rediness code was not set, apprently that's a common enough issue that they automatically send you to a refree station, which was very hassle free and cheaper than a regular smog station.

Smog the car...
How about now...I am going to try the road trip thing...then back to the shop for reddiness check. If it looks OK off to the smog station...if I fail, I'll take Robin's advice and go to a Referee Station.

I went to the track and it worked for me 
Ive also done the road trip thing at steady speed ('bout 240 miles) and that has worked. Its a total crap shoot IMO just drive it and see what happens.

The Track!!!
Great idea...I have a track date at the end of the month. We'll see how that goes.
I dread the thought of doing an EPA recommended Road Trip

Martin,
Keep in mind that driving according to the reset rediness code primeters is "dangerous to your life" in southern california. As most of the part you will be driving way under the "speed limit" and may be shot at by road ragers.

I just did my smog referee trip. Not worth the driving time at $4.00 gas and a sled like ride on the street for an uncertain outcome. Last time I drove over 500 miles and didn't reset the readiness codes...

The readiness setup in most cases needs to be done using the Porsche tester.
The "Short Test" needs to be done first for tank venting and secondary air.
If both of these don't pass, it's a waste of driving time to attempt any additional test.
If you need to set the readiness states, take it to Hergesheimer's as they know how to use
the Porsche tester to monitor the cycle flags during a readiness state setup.

Any suggestions for states that do not have "options" for smog testing?
I have had exactly the same issue - it's one reason the p-car is out of registration, off the road, and collecting dust in the garage.
I tried the drive-to-reset method and after 4-6 hours of stop and go driving - not enough.
Unfortunately Missouri went to an OBDII reader ONLY - unless someone in the St. Louis area knows of another method...

The only time I ever ever had my rediness code perfectly reset was combination of driving reset and dealer PST-2 reset. There are certain rediness reset functions that can be done by the PST-2, and I have ever heard that "CAN ONLY" be done by the PST-2.... go figures.
