I am a new crossfire owner. It is a 2004 coupe with 38000 very gentle miles given to me by my father. Engine light came on dealer said 02 sensor throwing hard fail. But numbers came back 9.0 and 9.3. They are saying should change pcm which i don't have a clue about. Car runs great no problems light went off and they said even hitting bump could turn it back on. What I need to know is I would like to take it on about a 3 hour trip since it is running so good would that be safe or am I subject to break down
