By your description of the fault you have a blocked or incorrect air filter in use. What is happening is a reduction in air flow and a leaning of the air fuel ration which raises the engine speed . Try a new air filter and check for blockage in pipe to filter.

The new filter allowing more air into the motor throwing off the air to fuel mix ratio you can either adjust the carb or put the factory filter on

Car idles very high when first started then a loud humming noise mechanic says its an air diverter valve

He is probably right. It is part of the fuel injection intake near the air filter. Change the air filter if it needs it and check the air filter box and make sure it is sealed correctly. There may be a gasket that keeps that box sealed correctly.

Engine idles smoothly but at higher rpm it faulters and back fires out of exhaust and runs rough

back fires out of exhaust implies too much gas at high end. caused by : dirty air filter, carb setup wrong(high float), ignition trouble.
a miss from poor ignition on the next stroke can be too wet even when the carb is set too lean so rule out the ignition problem. rule out the air filter problem. clean carb.

Idles high and low

Although it could be any number of things you may want to start with the air filter, a dirty air filter restricts the airflow to the engine and can cause exactly what you have described.

3 other suspects could be, Idle air control valve, mass airflow sensor, or throttle position sensor.
