Well, kinda piling on, but mine too sometimes cuts out on hard decel when getting back on the throttle. I'd like to hear what Marc says about it, as I too have the same issue with the secondary delete - have had for 6 years now. It can be aggravating, but only happens on
hard decel after running for "a while" in spirited driving conditions.
It isn't a big deal as it doesn't crop up all the time. But, I'd like to get to the bottom of it one day.
