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

Hi yer thanks that sounds like what's going on, did you get any codes or engine light Thanks for your help

I've tried to ECU reset and the throttle reset, and its had a new maf. Im in the west Midlands. Oh yer I've used that before Thanks

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.
