check you dont have a split in the corrugated pipe from the maf to the swirl chamber (the big black plastic tank attached to the inlet manifold) or a leak into the intake somewhere, doesnt have to be a small vac tube.
Also you may have a sticking TB butterfly as my learned friend suggested.

Sounds like the coil is going. The crank sensor will fire the ignitor and fires 2 plugs at once. Have the coil checked first. Good luck.

Try changing the ignition coil.
The easy way to test this, is turn the ignition on,for about thirty second's ,then feel the coil ,if it is hot ,replace it.

stalling issue at low speeds
is commonly caused by a dirty automatic idle speed control valve and
throttle valve. Buy a can of throttle valve cleaner from NAPA or
Carquest (made by CRC chemicals) and spray it into the air intake
while the engine is running, use up about 1/2 the can, engine will
try to stall hold the speed up, shut it down and let it soak for 30
minutes, restart and blow out the remaining fluid, shut it down and
disconnect the negative battery cable for 5 Min's to reset the base
