possable bad injector???

[tougemachine]

Ok, my car has been acting weard lately. It seems that I MAY have a leaky injector. The car has one of the cylinders seems to be louder at idle than others. And when I'm pushin it hard and I shift it sometimes backfires through the intake. Do you think it may be a leakey injector? Also the gas milage is decreasing :-(

sounds like the intake valve is not shutting completely while fuel is being injected. But it could be also a number of things that go along with that.
