Low Idle and Stall at Start

[luvmonterey]

Having a problem with my ‘94 Explorer at start-up. This doesn’t happen all the time, but is becoming significantly more frequent. Engine starts, but idle remains low, at about 400-500 rpm. When cold, it will sputter and die if I don’t keep my foot on the gas. Sometimes when this happens, the rpm’s will suddenly bump up to about 1000, where it normally should be at start. When the engine is warm at start, frequently the idle remains low, and not at the normal 600 rpm, but sometimes it starts and isles properly.

I ran a KOEO test and it returned a 327 CM code. I’m not sure if this is related. Any assistance would be appreciated. Thanks.

Dying right after start up? Weird issue, totally stumped. Videos

So my explorer has been acting up lately. Mornings when I go to work it will die right after start up unless I give it extra throttle, during the day when it seems warmer it might idle fine but die right when I put it in gear. other times it might just barely idle and buck and chug when I'm not...
