PLASE HELP!!misfire in multiple cylinders!

I have problems turning on the car when its cold.Idle is very rough then it will turn off and it will do it for a while till it finds the iddle,then the SES light starts flashing.They scaned and it said it had MYSFIRE IN MULTIPLE CYLINDERS.The computer is cutting off 2 cylinders and then they come back on,then they're gone,on and off.The car sound like ****,and performance sucks.The guy said that it seems to be an electrical problem,something with the fuel system.This problems were there before the cam, stall,and ls1_edit but it had gone away and now its back.What can it be.could it be a short?Please help me.
Thanks in advance

I would try swapping your plug wires around, plugs, etc.. and see if it will show that the misfire is occuring on different cylinders and if so then you know the problem.
