Default Ideas on stalling problem?

The last couple of weeks, my wife has noticed the car in the morning has been stalling or close to stalling.

Cold start idle is fine, will idle contently for a long time (don't usually let it idle for a long time however). When she puts it in gear the rpms drop off significantly and either stalls or comes close. Many times she makes it to the first light and it will stall there.

I've bumped up the idle speed 75 rpms, but didn't seem to help.

I frequently get the misfire 1-4 cel, but have had that for months, this problem is just recent.

Once she has the vehicle driven around for awhile, it isn't a problem. Warming up the vehicle (idling in driveway) seems to have little effect on the stalling (or near stalling).

Could it be running ultra rich to begin w/ and flooding the vehicle?

Any ideas where to start?

Thanks in advance.

what are your modifications??? do you have engine management?? also make sure your battery is good because mine isn't and sometimes it will start to die at a light and i have to give it gas to charge it back up...it sucks..but yeah i hope that helps...

Battery seems to be fine- starts right up, has been in the single digits already.

I'm wondering about the A/F sensor, evidently some think it's problematic in the misfire cels, and wondering if it "misreads" when cold?

Like I said it "cold" idles (higher rpms) fine, but when driven (early) it wants to die.
