Question about 1999 Mazda Protege
As soon as I put my car in reverse it starts running rough and acts like it's going to die (while sitting or moving) but it hasn't died yet. You can even feel it shaking. What could this be? I'm up to date on maintenance.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Check the fuel pump pressure while it is running and begins to die, the fuel pump has 2 circuits, one supplies power while you start the engine, the other after the engine is running, you may have an issue with the run circuit of the fuel pump.

The ignition coil should be fine at that mileage. If spark plugs do not fix it suspect a faulty MAF sensor. If the MAF is sending a bad signal it will affect with the idle as the ecu is trying to compensate for the MAF.

The problem is a faulty solenoid in the vapor recovery system. The solenoid is sticking open and allowing fumes from expansion of fuel in the fuel tank to enter the air intake and smother the engine. This is how the Mazda service tech explained it to me. It is a known problem on the Mazda 3 in various trims which Mazda refuses to acknowledge. Usually the check engine light comes on and the engine diag code reads mass airflow sensor, which is incorrect. I dealt with this for 6 months on my wife's 2005 Mazda 3i before the dealership figured it out. My cousin bought a 2007 Mazda Speed 3 which developed the same problem after a few months and was cured by the same fix.

check the fuel filter air filter and vacuume lines if they all good make sure the spark plugs are making a bright blue spark

I have a 1989 5-series BMW which sometimes stalls after changing from reverse to drive. It also sometimes shakes when first driving in reverse before changing to drive.
