1997 maxima starting/timing problem

[Duke1966]

when starting my maxima it cranks uneven as if the timing is off but when its starts, it runs fine. I had it scanned.It shows a knock sensor problem,a crank position sensor problem,EGR control solenoid problem,cam position sensor fault.Which one would cause this problem?

I would say the crank and/or cam sensor would be the most likely culprit.
