I have an 04 350z with kenitix intake manifold nismofull exhaust low compression pistons maybe forged rods etc anyways when I first got it it ran and started up like a new car since then I've had some codes pop up for o2 sensor, evap system and random misfires, sometimes at start up itcranks and tries to start but it sputters to an idle then runs ok until boost then sometimes it runs lean, but it seems to be flooding out at start up, I have the crappy tn reflash it ran fine last summer, I. Am gonna get it retuned when I get money also sometimes when I shut it off I can here. Gas gargleing (sp?)idk doesn't make sence to me,if someone has an idea please help, I was thinking about taking out the current walbro and installa new one with a fuel return kit so I know that its right but I have no clue sorry for this long sentence im on my phone, thanks

 

oh boy

 

Sell it and buy an new car. You don't even know what you got yourself into buying a used/built twinturbo'd 350z..

 

Your right newbie I havntbeen driving rwd turboed cars and nissan for over 6 years I don't know what I got my self into your so damn right can u please explain expert king? Pretty please

 

Obviously your 6yrs of driving and not working on them makes you an expert so why even start a thread with a question that your 6yrs of driving Boosted nissans would already answer.

Doesn't make sense.

 

Have you done any thing to try and find that answer to this yourself? i.e. a compression test, read the spark plugs, leak down test? those are some super simple test that some one of your vast knowledge and experience should have the answers to and would have put in the first post... just saying.

 

^ 6 years of driving nissans and boosted cars, nuff said.



Right?

 

park the car until you can afford to take it to an experienced VQ shop and at a minimum get a real dyno tune...
