Hey, I have Grand cherokee that I have recently purchased. I was on my way home this evening and while driving up my hill it started to surge. I then pushed on the throttle and It fell on it's face (total loss of power). It never died. The loss of power under heavy acceleration could be explained as a clogged fuel filter but the surgging while trying to maintain speed has me confused. 0Any help that you might be able to give would be greatful. Thanks.
