My truck is really rough idle when it is cold sometimes it even dies while idling. Once it warms up it does good. Also check engine light is on and we have it tested and it shows O2 sensor and we have replaced all of them and it is still on. What else could it be? We test it and it still says O2 sensor. Thanks for any help.
have the same problem?
