Stalling issue

First i notice a spark or arching on my distributor. Causing a bogging during acceleration only for a few miles clears up and drives fine . after work i started it up and took off the moment i pushed the clutch in it stalls out now if i start the car and push the gas pedal it will stay running i can take off and drive until i push the clutch in. When i push it in i hear a squealing noise as well the car ran fine up to this point what could it be ? I also have IACV unplugged have for a while now was having spikes in my rpm and i unplugged it ran fine. Is it timing electrical? I would appreciated any feedback.
