It's the plug about 10 inchs back from the actual o2 sensor, I crazy glued the plastic back together, then resaudered the wire, put the cap back on and remounted, went for 2 separate rides, things seem to be working well, accepted trims 2 x and on the 2nd very few adj, looking at my map now iam noticing a lot of negative values in the lower rpm range, I've got kick *** power when I twist the throttle but Ian noticing when I let off the throttle that iam getting a weird sound as the motor is spinning down not a backfire more like a wah wah wah (is this reversion I keep reading about?). it seems with the leaner value down low it's affecting my sound a bit, also noticed that my drivability is suffering while Iam motoring in first gear down my half mile driveway, a bit jerky any ideas?

Add some fuel to the lower rpm's. Did the trick for me. I don't have the AT but do have the woods cams with a 2-1. I noticed the same as you are here. Talked to Jamie and added some fuel in 5% increments. All it took was to add 5 to the value that was there from low rpm up to about 20% throttle. I think that will get you where you need to be.
