it then it shuts off? My 1999 Durango runs okay, has a slight miss but, gives me a misfire in cylinder 4. I have new wires, plugs, AICS, Intake Gasket, Distributor cap and Rotor Button, We have spent almost 80 hours and it shuts off at stop lights and signs for no apparent reason. The 2 cables from the throttle body sensor are loose. Could this be the problem? what could be the other reasons. Any help welcome.
