rpm / speedo
 

Hey All

Have a JXi and while in park the rpms will fluxuate 100 to 200 rpm at the same time this occures the speedo will jump from 0 to 55 mph. This rpm fluxuation does not happen all the time. The movements are not irratic on the speedo. This goes away after stepping on the throttle but returns a minute later. Let me know.
