My 99 grand cherokee, died on the freeway, felt like fuel issue. Tested fuel pressure.. now problem. pulled code 531,532,533, coil problem and cylinder missfire. Replaced the coil pack (the long bar 3 in one component).. got engine to fire and start, but ran rough and died when giving throttle...replaced cam pos sensor,,,, no diffrence.. now i have a 1391 code...aids its supposed to be cam sensor,, but cam sensor is new,, and even the old one does the same...only have 59,000 miles on it so it cant be the timing belt/chain....anyone experience the same????
