A/C on by chance? .... If so, when was the throttle body last cleaned? - Dirty throttle body may cause a stall under certain conditions or erratic idle.

It could have been a momentary glitch with your Idle Air Control valve, but just clean out the throttle body and if it doesn't happen again, then you're set.

From time to time my 02 dies with no warning and without any provocation and then fires right back up like it never happened. My 5.7L 98 and 5.3L 01 1500's did the same thing, I think the computer just brain farts once in a blue moon.

I agree....clean the Throttle Body, mine stalled last year and wondered why it did that, its an 06.....took it apart and it was dirty....once I cleaned it it was fine ever since.....

It's located in your throttle body... kind of like a super-small throttle body that controls the amount of air that bypasses the throttle butterfly when you're not on the gas... if it glitches and closes... then you end up stalling... of course, cleaning the throttle body usually fixes this by clearing out the passage the air takes.... and now that I've said all that, I feel embarrassed because I just googled that and found out we don't have an IAC valve... :duh:

Please excuse me while I extricate my foot from my mouth.

No prob. Just wanted to make sure we hadn't suddenly moved over to Civic-Ricer-land and we now had IACs to worry about. (My wife has a Civic, but not a ricer. Not if I'm maintaining it. :dielaugh: )

:eek:fftopic:

Now now... I loathe Hondas... they're either boring or obscene... but I had/have (until I sell) a Mitsubishi Eclipse Turbo, and it was go rather than show... Unfortunately, it's only been a month since I got my trailvoy, so I haven't had a chance to lay in bed and read the repair manual yet to find out the specs on this car hehe.

Ok back on topic...
