Post 93 mazda 626 rough idle

Hey you guys,

I hope someone can help me. I have a 93 mazda 626 LX . I drove through some water during Harvey and it's been acting up ever since.

When I first start the car it idles fine for the first 5 minutes, then the RPM drop below a 1000 rpm and it starts to shake,
sometimes it turns off and sometimes it don't. It drives fine when it's moving on the road, but when I get to a stop light
or come to a complete stop, it starts to shake and I have to put my foot on the breaks and give it some gas to bring the
rpm back up. I have already replaced.

1 oil and filter ( no water in oil)
2 spark plugs
3 spark plug wires
4 distributor cap / roator
5 mass air flow sensor
6 air filter

I don't know what else to check. This is the only car I have and I really need it. If someone can please help me
I would really appreciate it. Thanks
