Hey there.
Was the emissions recall that we got on the 04's and maybe early models suppose to be the version 39 software update, or were those two separate items?
I just had my emission recall performed last Monday, and a pulley reduction installed. I used to get the choppy idle issue maybe twice a month previously, but since I got it back last Monday, it has happened about 7 or 8 times. I've not heard of any connection to the pulley reductions, so I was wondering if the that recall was the latest software version. Also noticed my service mileage went from 5,000 to 6,000 too, but that doesn't matter.

 

Wow, I didn't realize I had missed the other thread started by Dominic in November. Looks like the recall did the same thing to mine that it did to several others.
