I just replaced my o2 sensor and my fuel pump because i hace been having a sputtering problem and the car has to warm up before driven. I put the new fuel pump in and it worked fine for about three weeks and is still working good. Well yesterday i put the new o2 sensor in because mine completly quit. When i put it in it was smooth for about a mile and now when you push the pedal it just floods and almost kills the engine. Can anyone help me with this problem?
