Solution?
Did a few things this weekend:
1. Replaced the temp sensor. While I read everyone's comments about resetting the computer, my sensor actually had a pin break off in the connector. Didn't see much other choice than to replace.
2. Replaced the ignitor. Some have suggested on other boards that an ignitor might be the culprit, although many more Honda owners have experienced faulty relay issues. It was easy to get to and my Haynes manual described a test for it. It failed the test, so I replaced that too.
Now she runs fine (so far). I drove normally today and it experienced no problems where in the past, I would have been struggling to keep it running. My theory is that I was fighting 2 different problems; a bad ignitor and temp sensor.
Some lessons learned:
1. Check the ignitor before the fuel relay. While the relay has earned it's bad reputation, it's easier to check and replace the ignitor first. Anyone who's replaced the relay, especially you guys with big hands, knows that this comes with a big PITA (Pain in the a**) factor compared to the ignitor. Trying to work my hands behind the dashboard after moving the fuse panel left a bunch of scrapes on my knuckles. Plus, I've found the Haynes test for the ignitor to be more consistent than the Haynes test for the relay, considering that the reason for relay failure is temperature dependent. If you wait until your engine cools to test the relay, you may get false positive test results.
2. Trust the error codes in the ECU. I'm kicking myself for not pulling the error codes earlier and ferreting out the faulty temp sensor. That tipped me off that I was dealing with 2 different problems.
Thanks to all of you for your advice and help. Please, pass the word along about the ignitor.
