i have a 1995 sohc neon, it sat without bein cranked for about a year, after i got it running again, it only went about a block the just died, figured out the cam position sensor came unpluged, pluged it back in and now it only gets fire to cylinders to 1,2, and 4, i have replaced the coil pack, the plugs and wires. its getting gas no problem and spark to 1,2,and 4 cylinders what else could it be?????

bad compression, stuck piston rings, leaking valve
