could a sporadic idle be caused by a bad water pump on a Mazda 2.5L?

It is on a 1995 ford probe gt. Idles sporadically between 1k to 1.5k or holds a steady idle at 2.5k. Vacuum leaks do not seem apparent and the Throttle body sensor is functional
adjusting the idle speed adjusting screw makes no difference. it is already on the slowest setting and still idling high
 
Idle timers for ford motors back in that era were always a problem. The idel timer will help to control the idle of the car when the pedal is not pressed down. Once you press the pedal the timer is no longer needed so it shuts itself off. Just have it checked and serviced. It's not a major problem it's just an annoying problem. Forunately they no longer use those old fasioned timers anyways. Just have it adjusted and you'll be alright.
