I drive an 87 9000S. Check your vaccum lines. A small leak can cause a roughness in the idle. Check your throttle plate assembly to make sure it is clean. You will have to remove the clamp where the air intake feeds into the throttle assembly. If dirty, some carb cleaner, a tooth brush and a rag will get the job done. If you have no vaccum leaks and the throttle plate is clean, try a bottle of Pro Guard or Techron Cleanup. That will help clean your injectors and valves. Ken Washington 87 9000S
