I had this problem when I bought my mx3, found the cause to be a sticking EGR valve, I applied vacuum with a vacuum test tool and that was enough to unstick the valve and has been fine ever since.
To replace the expansion valve on a 2001 Mazda Miata, first, ensure the AC system is fully discharged to avoid refrigerant exposure. Remove the dashboard or center console to access the HVAC unit, then disconnect the AC lines from the expansion valve. Replace the old valve with a new one, ensuring all O-rings are lubricated and properly seated, and then reassemble the components in reverse order. Finally, recharge the AC system with refrigerant and test for proper operation.
A compression test will show you if you have a burned valve.

There are many great sources on the Internet where you can find the crash test ratings for Mazda cars. Here are two good ones, www.internetautoguide.com and www.motortrend.com.
You can test a millivolt gas valve with a multimeter by measuring voltage across the valve terminals while the gas valve is energized. The reading should be in the range of 500-750 millivolts to indicate that the valve is operating correctly. Additionally, you can visually inspect the valve for any signs of physical damage or corrosion.
