Rough idle and occassional shut of when slowing down

Inmy 94 obd2 swap car it runs fine except when at a stop or coming to a stop. The car didnt run like this before it sat for almost 2 yrs before I had time to get to it. So im wondering what it may be. I did fresh tune up with taylor wires, rapidfire plugs, new pcv and fuel filter. I tried spraying around all gaskets to find a vac leak and found nothing so I dont know where to go from here. I was think the fuel thingy under the coil pack area or map sensor or maybe the crank sensor ????

If its OBDII get a DHP on it and scan it, see what sensors are reading weird when it's stalling.

"sat for almost 2 yrs before I had time to get to it."
Is the gas the same that was in it almost two years ago? No fresh gas added?
Maybe gas went bad. Sealed, I heard gas can last two years but if you have a loose cap or the system is open somewhere else,
it might go bad.
