I have a 1993 intrepid latelly i,v been haveing a problem with it when i drive her for awhile say an hour or so she will shut down like at a light or a stop sign then when i try to start it up again it will turn overand start but at a very low idle and i can have my foot to the floor now if i park it for awhile say 30 mins to an hr she will start up fine and run like nothing is wrong for say another hour i was told that the cilenoid was bad can that be the problem?
