One of the cylinders is missing. It doesn't fire sometimes and when it does, you get the backfire. Check the plugs. It should be obvious which cylinder is at fault.

SOURCE: transmission shifts at high rpms

Have your transmition fluid and filter changed that should take care of it. I have ran into that problem before and that handled it.

2004 chevy trailblazer power loss, high rpms, low ppms


Check the timing chain. Some times the chain will shift with worn teeth and get out of synch. This will cause the engine to lose power and back fire. Sometimes with a flame through the carb. I did that one once. Easy fix if it is the problem.
