yield

Over the last week or two my car has stalled when coming to a stop. It's only happened 2 or 3 times over that period but it's obviously not a good sign. It only happens when I'm slowing down and I take my car out of gear when coming to a stop. The revs drop down and just go a tad too far and the car stalls. After re-firing it's great again, and the idle is still smooth always, it just doesn't always catch it in time when I go into neutral.

I haven't done anything big to the car recently. I did a valve adjustment a few months ago and that caused me to idle slightly lower but not to the point it was shaking. I could just mess with the idle screw but I don't want to cover over a potential problem.

Any idears or should I just bump up my normal idle speed?

I am a pretty close problem to yours except my idle just goes crazy from 630 to 850rpm.
I know mine is the fuel pump after discovering it's not my FPR. And I am also throwing a CEL 43.

I dunno if yours can be related, but just thought I'd share.

You throwin a CEL man?

Also it COULD be the knock sensor going out. But then again you should be throwing a light. I had idle problems like yours when my knock sensor was going bad.

No CELs, car runs real smooth 98% of the time and then it will just stall once every few days

When mine started doing that it was the ignition switch that was starting to go. Don't know if it helps...

try this:

clean the battery terminals (do it anyways, even if you are sure they are clean) and let the ecu reset. i did this and until i ran my car like crazy for a week straight the idle would always go back to the perfect 900 rpm (i set it higher bc of the ES motor mounts)

Try that and see what it does then, but after you do it, wait atleast 5 or to minutes of "normal" driving before you give it hell to let the ecu relearn everything
