I hooked up my OBD II reader and it said i had an o2 sensor problem. So i replaced the sensor and it made my car run horrible. Once you get up to speed the engine floods and I have to gas it and clear it out. We took a look at it for a while then decided to put the bad sensor back in. When the old sensor was in it ran fine again but the check engine light comes back on. Any ideas?
