not sure what the code was it just said oxygen senser then multiple misfires on different cylinders the garage said change the plugs as the oxygen senser may be showing because of the misfires the engine management light was taken of and hasnt come back on but it still has a misfire and no power you can rev it when stationary in park and overcome the misfires but it is still lumpy and lacking a sharp pickup

engine light comes on sometimes only thing on it is oxygen senser and lots of misfires sometimes the car runs better  then goes back to not reving up and misfires or what seems like misfires im wondering if its a fuel problem like fuel relay or pump has anyone had these problems thanks
