As it turns out, by the time the Miata has a good number of miles maybe over 50K or so , the intake manifold can build up an excessive amount of carbon because of the exhaust gas recirculating and the crankcase vapors being drawn in. Alternatively, it can become bent or kinked. These exhaust gases are recirculated into the engine to lower combustion temperatures to reduce and or eliminate spark knock. Gas mileage is very bad.

It is located in the inside of the top manifold piece, just an inch or two behind where the throttle body connects to the manifold, on the engine side. I've noticed the gas mileage isn't what it should be. The new water-pump installed and bolted tight. That can be a mistake.
I thought I could just clean the port hole and replace the manifold gasket. . Is there any servicing I can do to it first? I've replaced on the parts on the egr side of engine.
