I turn the car in an it backfires. I changed the spark plugs and wires. I checked hoses looked for leaks. And it still does it.

These car had a problem with the rocker arms breaking causing the engine to back fire. This will require removing the valve covers and checking the rocker stands. Here is a guide that will help you get the cover off for inspection.
