The car missfires when accelerating upto 3000 rpm and is then ok upto 5000 rpm but will not rev above that.The car has had a new lambda probe cam & crank sensors 1 new coil was purchased and swapped round 1 at a time but still got the missfire, pulling my hair out over it anyone got any solutions

normally if its the chain a check engine light will come on and the code p0340 camtiming when it diagnostic checked, but if its not on yet it still might be early stages of it, to check chain bit more involved than looking through the oil filler cap, u really need to see how far the tenshioner is sticking out and most nissans have a small plate u can take off to see in or u could just remove the whole cam cover and look down, if its sticking out more than aprox 10mm the chain needs to be replaced,

when you drive the car without accelerating hard [normal use] have a look at your rev counter and see if it is steady or if it is moving up and down on its own slightly if it is doing this then your timing chain has stretched causing the symptoms you describe .you should be just able to see the chain through the oil filler to check
