RE: code reading?
I can give you an answer if you give me the code number. I cant do much for you if you dont give me the code number. But first guess if you have a 99+ Mustang you have a bad coil. ?they have coil on plug system

RE: code reading?
Each ignition primary circuit is continuously monitored. The test fails when the PCM does not receive a valid IDM pulse signal from the ignition module (integrated in PCM). Its for the ignition primary A. I'd check the first coil pack and see if its junk. try getting some MSD ignition coil packs ( or other brand) and then clearing the codes.
