engine idling rough on 2000 Nissan Maxima

I'm have trouble with a bad fuel injector. The engine runs rough at idle and acceleration. I was told it was a bad injector. Is there anything I could add to the fuel tank to clear this up? If it is the injector, how much of a job would it be to replace an injector, and the cost?

You can get this estimate at www.repiarpal.com/estimator put in your Maxima's info and choose fuel injector and you can find a shop here www.repairpal.com/directory
Lucas Oil Products makes an AWESOME product for this. Use their "fuel injector cleaner"! Follow directions on bottle. You may need to continue using this product more than one bottle.
