ok Im having a problem here with my cobra I recently put a build motor and car was running fine before, car started to give me a p2195 code I know its a o2s but I have replaced them and still have this code.I was suppose to tune my car and tuner couldnt tune it bc of this issue, I have also clean the wires and check for any burns but nothing??? I want to take it to a ford dealer and see if they can find the issue but I want to give it one more chance before I do that and if someone can help that will be really great:rockon:
