I recently installed the WMS intake, and it's run fine for a while now with no problems, so I don't know if that's contributing to the problem or not. - Also, Xcal2 w/ 91 tune, and I was running 93.

But, after driving to Ohio, and then running some arrands, I started having problems w/ my car. I was driving to put it into storage - it was raining - and the engine stalled as I was coming to a stop. The first time I thought maybe I did something wrong and just restarted and went... Then it happened the next time I came to a stop. So, I restart and go, and the next time I stop I'm sure to check that I'm coasting to the stop in neutral, and I watch the tach drop to zero, bounce to one, and then the engine shuts off. The rest of the time I made sure to keep some throttle when I came coasting to a stop and had parked it in storage hoping that when I come back everything will be back to normal. Any idea what caused this?
