distributor shaft
On the rear of the carb there should be a black plactic knob on a shaft with a spring. You will probably have to take the air cleaner housing off. Tightenen to idle up, loosen to idle down.
Check the cam shaft position sensor
on some models yes. it has to freewheel in idle, even though it's not driving anything.

a longer cam shaft will make a car idle rough
governed idle spring
It's a flex shaft with a Phillips #2 head, connected to the carburetor. It could be dangling because the mount is wire junk.
1,350-1,450 rpm (Shaft driven 2 3/8 turns out) (chain driven 2 turns out)
Check idle air control valve on throttle body. Mine had similer problems. A quick fix to get you going should be just unplug and remove spray w/ cleaner to get carbon off spring and cone shaft, reinstall. remember, this is just temporary.
Chances are the Timing gears or pulleys are not properly aligned. The Cam shaft and the Crank shaft must be aligned properly so that the valves and pistons are "in sync"
The Mazda Millennia Speed sensor tells the speedometer how fast the vehicle is traveling. Speed sensors are located on top of the transmission housing where they can reach the input shaft. The speed at which the input shaft spins tells the vehicle how fast it is moving.
