2002 Jeep Grand Cherokee after doing 70 mph when you begin slower speeds the Tach fluctuates and car experiences "hiccup". May do 4-6 times in a row before smoothing out. Replaced Cam, Crank and Throttle Position sensors, Coil Pack, Plugs and fuel filter. We are at a loss here.
have the same problem?
