p2305,need help shaky idle no power,coil shorted
 

please help

ok this all started about a week ago when it was running alittle rough and i got code p0301 and p0300 so i change plugs and wires not much of a difference and you can still feel it miss at idle.

and heres where i really ****ed things up, i take the wires off the plugs and put a old plug on a wire and hold it to the valve cover(ground) to check if they are getting spark and i left the other wires still conected to the coil and one of the wires i wasn't using ARCHED to the fuel rail ,then i put all the wires back on the plugs and go to start it again and its 2x as worse as before IT WONT EVEN IDLE unless you keep the rpms up,so i go check the codes and now i get code P2305 - Ignition Coil Secondary Number 2 Circuit Condition.

so i bought a new coil pack today and no change at all,i also checked all the fuses in the fuse box unless theres a hidden one somewhere and swapped around the relays no luck.

im out of things to try now any input its appreciated

car is a 2004 neon base 5 speed btw

is there a way i can check with my voltmeter if the coil is getting enough power?

changed the cam and crank sensor today no change.....

plugs gapped good, plug wires not pulled apart internally? clear the codes an see if it clears up. You can test the plug wires with an ohm meter to make sure they arent broken internally
