hello i have a 93 mustang lx 2.3 4cyl
and on the coil there are 4 plugs on each. while the car was running i unplugged one at a times off the coil.. and on 1 on each coil pack sparked..

No, that's how DIS works.

If you have more than one wire disconnected at the same time, that would be normal.
DIS fires one spark in a loop through 2 plugs.
If you truly have spark missing, then you could have a bad coil or ignition module.

When i unplug a spark plug wire while car is started nothing happens. there's only 2 plugs that if i unplug my car shuts off.. and there's no spark when i stick screw driver in the plug and crank the engine. Is that mean i have bad Ignition Coils???

Could be coil, could be ignition module. Needs further testing.
