Pretty much as the title says. It's and auto s1 stagea but still just a 25. All stock except bov have been plumbed up. had this issue before I did that. Read heaps of forums and did most of the things suggested (cleaning aac etc) afm seems fine but hard to call. Any ideas? It's drivable but will stall out when you back off at a slow rolling speed so I pretty much idle through carparks.

have you set your idle correctly? get the car up to temp stop the car...unplug the tps....start the car...turn the idle screw on the aac valve till you have it idling at 750. turn car off...plug the tps back in.....if it still runs like shit after that it could be your tps.

Cheers badgaz will do that in the morn. Bov has been deleted completely and made a new intake pipe

Why?

Put recirc bov back on.

The reverb screws around with the airflow meter reading leading to the issue you have described.

Well, your initial post isn't particularly clear. I suppose you are in a rush for people to help fix your problem.

Somehow bov plumbed up equals blocked off?

Was it previously the stock bov recirculating as per stock?

I usually pretty much idle through car parks also, lots safer than boosting through them.

Superben. Firstly thanks for a mature comment. the engine was completely stock in every way and had the ssame issue. As for the bov, New intake pipe deleted that line, blocked other lines and put a plate over the bov where it goes into the manifold.

It's not the issue.

As for idling through Carparks I have no issue with that. It's a daily running stock boost. It IS drivable. just any speed below around 50km if you completely release the throttle it will die the revs down to almost a stall.

Productive comments are appreciated. if not fk off to boostcruising. Cheers

Typical as the new guy to a forum you would ease into things before potentially offending knowledgeable people who were willing to take their time to help you.

It's pretty hard to judge someone's true character based on a few (or even alot) of posts.

Not sure if your trying to have a dig or not. Signed up and posted in hope of getting some useful feedback from other owners, which in fact I got. The other comments are useless and there's no need for them. I referred to boostcruising for obvious reasons. I thought maybe a website dedicated to specific cars might have been a little different. Maybe your all having a lend and think it's funny? Sorry can't tell, this is text after all. I have stated that positive feedback is appreciated and will continue to thank those who are actually knowledgeable and offering their help.

+1 for BOV not helping the situation.

I have an auto R33 atm and since putting a Blitz atmo on back off it almost stalls. But I live with it for the hektik doses it does :yucky: ..

I'd be pressure testing the system for leaks as they will also create stall issues along with the bov set-up..

      The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.

      Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?

      You can probably scrub the rust with a toothbrush or something. After you get the rust off flush well with water to neutralize and you will probably want to also use a fuel tank sealer to keep it from rusting again.

      The sodium citrate solution is designed to buffer the citric acid to keep it from attacking metal quite so much, the guy that came up with that recipe did a ton of testing on how much metal loss occurs over time and it's nothing crazy unless you forget about it for months:

      Dumb rich kid tries modding for the first time

      By Hexi · Posted

      Ohhh I see lol To be honest the main reason why I wanted to start modding is because of a business trip to Japan and Indonesia. I saw many cool and modded cars all throughout in these countries, especially Japan. I myself am of Chinese+Japanese nationality and when living in china (never lived in Japan js my dad side lol) I remember staring at these cars pass by with their loud tacky exhausts and insane wide body kits. And when I went back to Japan, I got even more invested even asking people about their cars and why they modded. Most gave similar answers to what you said but funny enough one guy just said that he saw the need for speed movie being filmed once in Tokyo I think near Shibuya Crossing and got inspired to tune and mod. After that I just started to fantasize on owning a car like that. Also tbh I prefer the R32 over the R34 it's just the R34 is more iconic lol (also apparently better aftermarket support than the R32) and my only goal really is just to make the car mine and make it fun to drive. As much as I love my Cayenne it's pretty bland to drive. Sure the interior is nice and pretty, gives you attention yada yada but I've wanted to experience what it is like to have a car that is truly yours. I suppose thats the goal so far. Haha if you find where I'm from, then sure. Ill help you out on your next "financial decision"
