Ok i got a yj 2.5 auto no check lights on but when i start if its fine but when i go from p to r it cuts off if i give it some gas it will stay on . I can go from n to r and it starts to cut off but stays on , when i am driving and come to a stop it strats to some time not everytime and when i rev it up it will start to cut off also . I am going to change the fuel filter and check the plugs what else ?
