Question about 1984 Mazda B-Series
You need to remove the air cleaner off of the carberator,unbolt the top and remove the hose by just pulling it out.Now that you can see the carberator you need to locate the throttle cable on the drivers side of the carberator,have someone press the gas up and down foy you and you will see it move.Now the you've found the cable then the part that it goes into has a stop on the rear of it that rests on an adjustment screw ,undo the jam nut and turn it in 1 turn and the try the idleing.Keep doing this one turn at a time until it sounds normal to you or until you get to 750rpm.s.If none of this helps the you may have a vaccume leak or even a stuck pcv valve in the valve cover,i can't think of any otjer common causes,these trucks are normally problem free.
