We bought the car recently and discovered it has problems. I have replaced o2 sensors the vacuum pump and breather valve. While I was testing the old vacuum pump I had only thhe p0492 and p0491 codes showing up the vacuum pump randomly quit working and then the p0014 code showed up. What do I need to do to help resovle this so I can get it to pass emissions?
have the same problem?
