Question about 1988 Mazda B2200
Usually that's caused by a vacuum leak near the manifold area.
Sometimes air in the coolant will cause an idle problem. Air will keep the air temp sensor from sending proper info.
Hope this helps.

Need to adjust idle speed by turning air adjusting screw on throttle body idle should be 750 - 790 RPM. make sure spark plugs and wires okay. make sure distributor cap and rotor good.replace fuel filter do a little tune because if engine not fine tuned one bad cylinder will cause engine not to idle if you have fuel injection system clean fuel injectors by filling gas tank full add a can of seafoam to fuel tank see what happens.
