Just had something similar to what you describe with mine. Took it to horsham and they diagnosed it (i may get this wrong) as a sticking valve? To do with the variable valve timing that connects to the end of the camshafts, they said it was fairly common and when it sticks the revs can drop then the cams are out of timing and the ecu tries to sort everything out resulting in the stuttering and loss of power and what seems like mis-firing.
Good news is they mapped 90% of the issue out and my car drives much better now with all the power i had previously plus 2bhp more.
bad news is a new replacement vvt bit costs £1000 upwards if i decide to “cure” the issue rather than mask it. I have probably explained that all wrong but like Alex says, one of the traders/tuners on here will be able to tell you the exact issue if you pay them a visit, does sound exactly like my issue though.Hi yer thanks that sounds like what's going on, did you get any codes or engine light
Thanks for your help

Hi
Unsure if its even a cylinder that is at fault, All coils are firing, If I was to run it on 5 coil packs And do this across all 6 cylinders, disconnecting one at a time all the cylinders sound the same.
It's almost like the timings out. When warm it idles at 600 rpm
It's hard with no engine codes
On a american website Someone said It could be the cam sensors, but I'm not a fan of guessing.

Hello has anyone got any ideas, I've tried all the usual things.
I was out in my 2004 350z, It was running fine nothing wrong with it. as I came into a village an I slowed down As I came out the village put my foot down and it ran horrible.
Its sound like its a misfire but not misfire its running rough no power. No engine light is on an no codes are stored, It's had new spark plugs new coil packs new injectors and the solenoids have been cleaned out no change. And I've done a compression test on it The biggest difference across the 6 cylinders is 10PSI, I've also check for vacuum leaks, Fuel pump is OK.
I work with cars myself but I've never come across this.
My 350 is running horrible

OK well mate I'm going to have a look into that, also my mates the lightest snap on diagnostics scan tool going to try it see if anything else comes up , you do more with it. My scanner is cheap mac tools one cost about £80 only really good for reading in deleting codes, So I will get back to you if need any parts.
Thanks for your help
