Does anyone have any idea why my 2011 370z would run ruff and feel like a broken 4 cylinder? engine mods cold air, extractors and cat back exhaust.?? Sent from my SM-G930F using Tapatalk

I have a 2010 stock 370z and it too stared running really rough last year . After thinking the worst. Realized the battery was on its way out and the engine was not getting a nice clean spark. Changed battery and back to being brilliant. Sent from my iPhone using Tapatalk

You spend $6k with a mechanic who has not fixed he problem and not read the ECU codes ???  He's clearly hopeless...

You're now worried about a $300 ECU diagnosis (which should have been done much earlier) ???

You post asking for ideas without telling us what remedial attempts have already been done to date ???

Hmmm...

White smoke is normally coolant being burnt (things like blown head gasket or even cracked head).

If you can smell oil it's either being burnt and going out the exhaust or the engine is wet with oil evaporating due to heat.

Burning oil will kill the cat's and they are likely to clog causing a loos of power at the very least

I doubt the solution will be found on the internet - best to take it to a decent service centre

      Hi Tony, just saw your post, although it is over 6 months old now. Did you end up getting your roof sorted? If so whereabouts. I own a Roadster, live in Newcastle and am having an issue with the deck lid hitting the roof 5th bow.Still opens and closes fine for now. It appears to be a very common problem as I have following the ongoing US 370z forum on this matter. There is actually a Nissan service bulletin out for this plus others for roof issues. Rodd

According to fast intentions the stock water cooled oil cooler will hinder the effects of a front mount air cooled oil cooler. There’s a thread explaining why they say it’s best to remove the stock cooler  when fitting a front mount cooler if you feel like googling it.
