Hi, I've owned a 2005 350RX Stagea for almost a year now and I'm finding that it seems to be using more fuel than it used to, and generally feels a little less responsive and less smooth. I'm somewhat open to the idea that it's all in my head, but while I can get up to around 10-11km/L on the motorway, around town I tend to get more like 6-7km/L and that's going very easy on the loud pedal in both cases. 10-11km/L would be strictly motorway driving. I just did a 1000km trip on the open road, and throwing in a few corners and a handful of 50kph zones through towns and that averaged out to just over 9km/L I bought an OB-LINK a while back and have been using that to try and track if it was something to do with my driving style, but it seems like it just likes to suck fuel if you're doing anything other than sitting at a constant speed on the motorway. What I noticed this morning though, was the meter for "A/F correct 1" and "A/F correct 2". I assume these are the two banks, but while A/F correct 1 jumps around a fair bit as you accelerate and decelerate, A/F correct 2, seems to spend 99% of the time at 5%, with very occasional jumps to 10%. I'm not entirely sure what the percentages are supposed to be, and I haven't got any error codes, but I'm wondering if this could point to a problem with the bank 2 O2 sensor? The car has never felt like it's misfired, but there have definitely been times when it's felt like it's running rough. Do these sensors fail in this way or are they either going or not? Any suggestions? Cheers, Tony

Hey guys, got my series 2 rs-four stag about 2 months ago, loving it i must say! Only thing i don't love is the fuel consumption, i have just done 330km to just under a full tank and i spent 90% of that time off boost. Alot of people talk about it being the O2 Sensor, so i pulled mine out to check the condition of it, to me it seems in pretty good nick (car has done a touch over 100k's). another thing is the guy i bought it from lived way out in the country side, and i live in the city, so an ecu reset is probably a good idea, but after 2 months i would have thought the car would have adjusted by now. cheers matt

Just read the codes and got; P0150 02 Sensor Circuit Malfunction (Bank 2 Sensor I) P0151 02 Sensor Circuit Low Voltage (Bank 2 Sensor I) P0160 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 2) P0162 02 Sensor Circuit Malfunction (Bank 2 Sensor 3) Is bank2 driver or passenger side? Are there really 3 sensors per bank, so 6 in total? (dafuq?) Given that they all happen to be on one side, i'm guessing its wiring.

RB25DET NEO stalls once its warm Hey guys my RB25det R34 has recently developed a problem where the car decides to stall once it is warm, this tends to be when i am at traffic lights stopped or crawling pace, has also happened when ive been in the lower rev range but i have found that so long as i keep the revs above 3k rpm it doesnt happen. i have checked coolant temp resistances and they all look about right when cold its 3250 ohms and warm 230 ohms. The wires to the o2 sensor have been cut for as long as ive owned the car and worked fine for 2 months then started this problem so key points, -Dies once warm -Coolant temp sensor looks good -seems to be fine with higher revs car specs: STOCK RB25DET NEO with fmic, turbosmart bov to atmosphere, link g4 ecu Thanks in advance

OK, so I'm aware this is an age old discussion, but I'm trying to get better fuel economy from my R33 and wonder what I'm missing here. Firstly, engine mods are - full exhaust, Blitz panel filter I was getting around 330kms/tank and decided this was pretty poor. I then replaced the O2 sensor on the assumption that it should have been old enough to be not working at its prime. This gained me only about 30 extra kms/tank. Now at 360kms/ tank I have recently added a bigger dump pipe and metal cat, making it a full modified exhaust which has not really changed things (that's not why I installed them, though). The AFM I would have cleaned about 10,000kms ago and I would have thrown in a can of quality injector cleaner for good measure about 5000kms ago, so while I will do these again soon I don't expect much/any change. Spark plugs are around 12,000?kms old, and would have been platinum/iridium? So the big questions are 1- What OEM parts should I change/maintain to bring fuel economy back up to what it would have been designed to give me? 2- What else can I do to improve this? Thanks

Narrow band o2 All, in theory can you install any narrow band sensor by making the connection end fit wirinh loom? i understand narrow band will be sending lean or rich signal thus should be using a stanadard voltage to communicte this meaning any ecu can understand any o2 sensor, am i correct? reason to ask is i have a narrow band sensor on the r34 and have just purchased a wide band. i want to replace it and install it where the narrow band sensor is right after turbo and then from the controller feed the narrow band to ecu until i get my link ecu in which can will use the wide band output many thanks

Hi guys, up for sale is my WBC 2 wideband controller. I installed it on my car but then changed from twin turbo to single so took it off and got the single O2 kit. The car has started with the kit on but it never left the shed so it should be in really good condition. It also comes with the dual display gauge so you can see what your AFRs are sitting on. The only thing you'll need are new weld on fittings for the O2 sensors to screw into the exhaust. You can get them on Ebay for about $10 each. I believe this kit is more designed for Platinum range of ECUs rather than Elite but do your own research to confirm. You can just use it as a standalone to monitor your AFRs. Price is $250 and includes delivery in Australia. Its on Facebook and they hungry on there so let me know ASAP if interested!
