. I have a 2010 250 4x4 5.4 6-speed. Truck has rough idle, bucks and hesitates.

Yes. Everything seems to be fine on vacuum leaks. It's intermittent. I didn't write down the exact code numbers. But there was about 10 codes. Mostly saying cam retarded or cam advanced on banks 1 and 2. And one code said misfire on cylinder 3. It will run smooth and be fine then all of the sudden it just starts bucking and lunging. Sometimes from the start sometimes in the middle of the power curve......Well ended up taking a gamble. Replaced the crank sensor. No change at all. So I changed the right bank cam sensor. Boom! Just like new, runs like a top. Wish I would have changed it first. Takes about a minute to change. Crank sensor took about a hour to change. :-(
