Was the car running when you started this work or are you trying to get a car going that you just got?
What did you get when you scanned for codes? What do you mean by 00 and err 2? Doesn't sound like the scanner successfully made the connection. You need those codes. You probably have misfires and you need the codes to find out which cylinder. When you disturb old brittle ignition wires to change plugs, you can break them internally.
