RE: ABS and Idling Prob.
Just for the sake of discussion, one way of knowing if your rear ABS speed sensor is bad, is the speedo drops below 25 mph. The PCM and ABS system uses the rear ABS speed sensor to measure vehicle speed under 25 mph. If it went bad , ( in one case) your speed wouldn't move until you reached 25 or more mph....
