I have a 1995 Isuzu Rodeo. Recently, the speedometer has stopped working. So the speed is always shown at 0 mph. Also, recently after driving for a while and slowing down to make a turn,the engine will die...I can then just put it in neutral and restart and go. Doesn't happen alot. But at least once a week. Any ideas as to what could cause this? And if anyone else had the same issue, the estimated costs to repair? Thanks!!
