Thanks for the advice but its bone dry. No water leaks from the seal on the crowl where the hood shuts. We haven't had any rain for about 2 weeks also. I switch the old one back on and drove about 20 miles let it sit for awhile and drove for another 20 miles or so. And I have no codes come up when I check. Weird something's up.

I dropped a set of plugs in the Ex a couple of months ago and immediately wound up with a #10 misfire. The cylinder wasn't dead, just not "right".
It turned out that when I pulled the plug off of the #10 injector (to get my big old hands to #10 without breaking anything) the retaining clip on the plug broke. When I reconnected the plug, it appeared to be in place but it wasn't making a good enough connection to generate a consistent fuel flow and power.
The onboard electronics picked it up and signaled a #10 misfire.
It's an easy thing to check!

Funny I replaced all my sparks today and I restarted it and it wasnt running right again. Played with all the boots a little wiggle here and there and then I noticed the plug to the ignition coil was cracked making a poor connection. Replaced it good to go. Thanks all for your advice.
