I recently bought a used 96 altima which has been giving me a good amount of trouble. It takes a very long time to start up, but does so consitently. About a month ago the check engine light came on, and the car began to "rumble" and sputter at idle.Ignition wires, plugs, filters etc were all replaced. Problem was not solved...Then had fuel injector on the 4th cylinder replaced which seemed to have solved the startup issue as well as the idling problem, until a couple weeks later when both problems returned. The check engine lights ive gotten recently were: multiple misfire then oxygen sensor a week later...today when it came back I checked the ecm codes myself and got code 33 (oxygen sensor?) and 65 - 4th cylinder misfire. any ideas? the front oxygen sensor looks fairly new. are these problems related?
96 altima o2 sensor and misfire problem..plz help!

Hello,
Check the intake manifold gasket were the manifold bolts to the head. That year altima has been known to blow the gasket around #4 cylinder. You can spray some carb. cleaner along the gasket area and see if the idle changes.
Hope this helps
