Electronic ignition conversion help.

well, the reason i was wanting to get the electronic ignition conversion to satbilize the voltage is, the car runs rough, partly because it needs a tune up pretty badly... the voltage pulses with the engine, thats why its inconsistent... and the car has a new alternator, battery, and terminals.

are you sure the car has an electronic ignition? would the conversion be an upgrade for it? im gonna go look here in a minute to check it out.. the car is getting a tune up thursday or friday after i get my pay check, and new shocks all the way around.
