Ok, I had the battery disconnected for 40 mins, then reconnected and followed your procedure exactly. Then I drove about 70 miles on the highway, and it stalled again while driving around slowly in town.
When it stalls, it happens when going slowly, then getting of the gas and coasting to a stop, or while stopped then about to go again, just as I start to get on the gas a little.
I read somewhere else that my MAF sensor maybe dirty from the oiled air filter. I have a pretty clean Steeda CAI filter now, but the K&N it had when I bought it was over-oiled I believe. I cleaned it since, then put it back in when taking it to the dealer.
I will be buying a OEM paper filter for bringing to the dealer from now on, as that is "aftermarket" as well. It's just funny that I bought it "certified" from the dealer with the K&N in it.
Anyhow, I'm going to spray some MAF cleaner in there, let it dry, then see what happens.
If it keeps up, I probably have a leak of some kind. My hoses look fine, and since this all started when I swapped back to stock, I think handling the MAF sensor may have knocked some dirt/oil into it or something, at least that would make sense to me vs. some sudden vacuum leak.
Then again, I'm just learning about all this stuff, so I could be wrong!
