Just replaced all injectors and coils and number four not firing at all. Can unplug coil and makes no difference in running. I ordered a used ECM and now rethinking that. The one I bought has the exact same numbers on it but now I was told I may have to have it programmed. Is programming a big deal and what is cost. This car was given to us for a second car and run great until this problem started. Any suggestions?
