Hi all,

I couldn't find my prob in the search topics, although it probably has been covered. The car is acting like it has a massive induction leak somewhere, however I can't find it anywhere.

Basically what happened was as I had taken off from the lights in a quick manner and got to around 3000rpm, when suddenly I had no power (as if I had blown an intercooler pipe off or almost ran out of fuel). I backed off immediately and on deceleration and light acceleration everything acted as normal. Although the turbo builds pressure, as soon as it does the engine starts to die. I managed to get it home and began diagnosing when after 3-5ish mins the engine stalled and would not start again. This morning I went through and checked all of the pipes and connections on induction side for leaks. The car started as normal idled normally for about 3 mins then started idling rough. I cleaned the afm then tried again and achieved the same result.

So i'm not sure if its the afm (gave it a clean and no difference), bov stuck open, or something else. I use the car for work, so I am stuck without it. Any help would be greatly appreciated.

Adam

Also, engine diagnostics give fault codes 0100 - Mass or Volume Air Flow Circuit Malfunction and 1805 (don't worry about this one - brake pedal sensor mod). It had been giving 0171 - left bank lean for a while, but not now. FYI engine mods are pod filter, fmic, bov, boost cont, radiator, thermo's, plenum spacer, turbo back exhaust.

Sounds very much like AFM, & given the pod filter I'm not really surprised. But the AFM's do give problems to guys running totally stock, so could be just one of those things...

Recent thread (first thought to be blown turbo). http://www.skylinesaustralia.com/forums/topic/420866-m35-blown-turbo/page-2#entry6771732

Thanks Commsman. I just read the post and it sounds about right. I wouldn't mind borrowing someones afm to test just to be sure...if someone is nearbyish or hornsby area. I'll play around with the connections, etc now though and see if there is any improvement.

So, I cleaned the afm and tinkered with it a bit with no prevail so I ordered a new sensor from Nissan. Cost a painful $309 and 10 working day wait.

YIKES!

I bought one from Amayama for $112...

      This could be sold and shipped to the US for many gold pieces. RMS has no say in that. Ask various Western Sydney inhabitants how it works.

      Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛

      Their 240Z with the RB26 would be a real nice thing to have in a garage to come out for an occasional weekend cruise It's such a cool thing in so many ways Sadly, we have a blue 240Z shell that I walk past every day, just sitting outside a shed at work, it has been slowly disintegrating and falling apart into the ground for the last few years, the owner cannot be found, and I am unable to "claim it" I've been told by work and the RMS, the rust in the body is excessive though, and it has had most of the salvageable stuff, like panels, trim and switch gear stripped off it over the last year or two, work keeps threatening to put it in one of our metal scrap bins, I wish they did though, as it makes Mark sad walking past it

      Good tips, I like it! 😂😂 My wife is a LOT more frugal than me so it's only me we need to worry about! A splurge to her is buying 2 pairs of socks in one visit at Kmart!

      Haha, the appropriate response to the question "Is this new?" is "I've had this for a while.". With the unspoken small print that a while may be the time since this morning or five years ago   And to be fair I learned that from the best, i.e. my wife. Because it goes both ways.
