i have a 200 nissan maxima it has less than 110000 miles. i've changed the spark plugs, and the engine light only shows that the oxygen sensors are bad well only one of them. the car has no power SOMETIMES. the engine runs very rough and shakes but it only does this a few times during the day . i've had a mechanic look at it but of course the car runs great every time i bring it to the shop. what is my POS'S problem. oh and i did use the correct spark plugs for my car.

 

Did you get this resolved?? I am having the same exact problems with my 01 maxima.

Thanks
