This is going to sound bizarre, but for about the past 4 months or so, when I first start my car in the morning and drive a few blocks and stop (say at a stop light) at idles REALLY low (around 200RPM). If I keep my foot lightly on the gas, it's fine. However, the other day, I didn't and it stalled. Starts right back up with no problems and initial start is fine.
The ONLY thing I can think of is that it happens when it sits outside. It's a 99 SUS Ltd. Sat outside until May of last year when I moved to a house with a garage. Bizarre as this is, at first I thought it was the air in Hershey PA. I travel there for work and when I come out of the hotel (generally once/week), I have this problem while driving the few blocks to the office. Come out at lunch, it starts right up. I know, does this sound REALLY strange?? Thought it was only when it rained, but last few weeks, no rain, just overnite moisture I guess, and it had these symptoms.
Yet this morning, my car sat outside all weekend in the snow and it started up and held just fine... so maybe that blows my dampness theory.
Anyway - I'm going to the dealer for an inspection and oil change Friday and they're going to look in to this but thought I'd try to solicit some input from here first.
Thanks!
