Engine Dying?

[ACSPONY]

This morning, I pulled into a parking lot to get something out of the glovebox, put the car into park, and it died. The engine cut off. So I started it up again and it turned over no problems so I drove off. Did it again at the store but started up fine. From then on it was ok, no stalling and everytime I put it in park it stayed on as it should. I did the "fog light mod" last night and disconnected the negative battery cable. Did I not tighten it enough?

Why don't you check the negative terminal? Anyway, it is probably your IAC. Replace it...

Doesn't the IAC control the engine idle? The car idles fine, rpms stay consistent and I've never had any problems before?

 

[ACSPONY]

ttt. anything besides the IAC? why would it crap out now? I don't want this thing to sh1t on me while I'm driving lol.

Well, maybe it dying that one time was just an anomaly? Perhaps it is fine...

Disconnecting the battery cleared the PCM's KAM. When it is reconnected the computer has to relearn all it's parameters. It is rare but when first reconnected, the car may stall as the PCM relearns the idle speed parameter. If it doesn't happen again, your ok. IF it does well then you can start looking at maybe IAC valve problem or something else for that matter.

Thanks Topless and Kilgore for the replies , it hasn't happened since this morning so I'm crossing my fingers I'm good to go.

When your IAC valve goes bad (at least when mine did) it begins as a VERY intermittent problem; however, once the engine has reached its operating temperature, the IAC won't cause the engine to die. Again, this is what mine did; I had to give it throttle until it warmed up, then it ran fine. If I stopped for a few minutes and restarted, it started up without a hitch.
