I put the car on neutral and step on the gas and heard the backfire!

Does it backfire when driving down the road, does it do it a lot, a little, when was the last time you check your spark plugs?

what about your check engine light -->
If it only does it in neutral the it might be semi normal since when you rev the car in neutral the cylinders are being loaded with fuel. When the rpm comes down the exhaust valve causes the excess fuel to burn causing the backfire.
Otherwise it may be time for a tune up...(vacume leak,timing..or 100 other things)
so if it drives smooth, and you cant hear it in the car then maybe things are good...
