200 Intrepid ignition problems

I have replaced the #2, 4 coils but motor is running rough. When I unplug the wire from the other coils it affects the motor, but these two do not. Got a stethoscope and and can hear a ticking in the coils. Had to replace the timing belt and ran into this problem when it was fixed. It runs when I take it out but runs rough on idle and nearly dies at stopping. Took #2 plug out and it was not as hot as the others, could the injectors be bad? I have 2 new ones. The coils could be firing but if it is not getting fuel it would not make a difference if you unplugged the coil wires, right?
