New Z Owner in need of some help

[Rolls]

Hello everyone,

 

I collected my first 350z recently, a car I have been eager to get for a very long time. 

 

However there are a few troubles with the car. It is misfiring bad, idling at around 2.5k RPM, then cutting out.

 

The car is a 2006 import. It has had a non rev-up engine swap at some point. 

 

It is showing error codes P1078, P1084, P0078 and P0084. (Which relate to the exhaust vvt solenoids and cam sensors) 

 

I can confirm that the previous owner had it running properly with this engine fitted so I don't believe it is a loom issue.

 

As the non rev-up VQ only has VVT on the intake side, any idea as to why these error codes could've popped up and how to resolve?

 

Thank you all in advance, really appreciate any tips or ideas.

Hi and welcome along buddy, I can't help you out on your issues unfortunately, so good luck with your venture. I am sure some of the more knowledgeable members will be along soon enough to help you out. Let's see some pictures of your new cool whip though!

Did the ECU's get swapped too as they are different - I'd look here first

 

If not that then the symptoms also suggest low oil pressure, how does the oil pressure gauge look?

Hi Zane,

 

First of all thank you for the advice.

 

How would I check if the ECU’s have been swapped?

 

Oil pressure sits at 6 bar at 2k RPM upon start up, before cutting out. Does that seem normal to you?

 

Once again really appreciate the help.

Firstly, to the forum.

 

I am sure that I can help you with this issue, but I require a bit more clarity.

 

How does the car drive on the open road?

 

What do you mean by "idling at 2.5k rpm?

 

Has the 112mph speed restrictor been removed?

 

In the meantime, I would recommend that you delete/clear all the stored DTCs

 

Then I would induce the fault a few times, and then check for any new DTCs and then report back.

 

 

 

 

 

 

However there are a few troubles with the car. It is misfiring bad, idling at around 2.5k RPM, then cutting out.

Thanks for the welcome pal,

 

I am unable to drive the car. It starts, the revs sit high (around 2k RPM), then within about 20 seconds the revs drop to about 700 RPM while the engine splutters then it cuts out. 

 

I am unsure if the speed restrictor has been removed. Forgive my ignorance but is there any way to check other than going that speed haha?

 

I have cleared the codes, and the two that have returned are P0084 and P0078 which relate to the Exhaust Valve Control Solenoids on Bank 1 and 2. 

 

Thank you
