I have an interesting problem with my '05/automatic. If I turn the key to the "ON" position, then turn it back "OFF" without ever starting the engine, then the next time I start the car it won't idle. Anytime I take my foot off the gas (and I'm not rolling down the road) it will instantly stall, as if the fuel was completely cut off. Other than not idling, it runs just fine.
Now, if the car is in this non-idling mode and I rev it up to approx 4500 rpm while in "Drive", then it will go back to a perfect idle and won't give me any trouble until the next time I turn the key to "ON" without turning it all the way to "Start". Revving the engine while in "Park" doesn't fix it, only when in "Drive". (no, I haven't tried "Reverse")
This was an intermittent problem that just seemed to come and go occasionally, and I thought that I fixed it a few months ago when I replaced my battery. When it came back this last time I wrote down everything I could think of that I had done leading up to the problem and everything I could think of that I had done prior to it's being "fixed". A few experiments later and I have the situation described above. This is VERY repeatable. It never happens without me turning the key only to "ON", and it's always fixed by revving the engine in "Drive".
Anybody have any ideas of what could be the cause? Thanks in advance for your help.
BTW, I think that this may be the first time I've ever started a thread!
