1995 Ford Probe GT mileage: 124,200.My car misses and idles very roughly.The idle will drop down suddenly from about 900 rpm to 400-600 rpm then pops back up again. It has had degrees of this symptom for a few thousand miles, possibly dating back to when the battery failed and had to be replaced.A dealer tune-up and a couple bottles of gas treatment have not made things any better.
