I find i'm replacing the O2 sensor on my car at least every 20,000kms....does anyone else seem to go through them that quickly? The AFRs aren't anything crazy currently (used to happen when stock as well)

I get the same symptoms long before the check engine light ever comes on, stalling at lights, stalling if braking hard, erratic low idle that doesn't respond to AAC adjustment.

Running the O2 sensor diagnostic to check the recommended "5 flashes @ 2000 rpm" and always get zero flashes, replacing the sensor and I usually get 7 - 10 flashes straight away and car runs like new again for another 20,000kms.

Bloody things are starting to become a general service item for me.

just unplug the o2 sensor mate..the car will run in safe mode which means it will just run a little bit rich but u wont be getting the problems your getting and you wont be forking out money to buy 02 sensors ever 20000 kms...thats what ive done and its fixed the problems.

yea, I ate a few for awhile and couldn't seem to beat it. We thought about fuel as an issue, and then heat. I noticed that everything around the sensor was cooking, so I fitted a body washer between the oxy sensor and the pipe. Then I wrapped the pipe and this seemed to keep the thing cooler and its been in there for two years now..

I can't, my fuel consumption falls through the floor, 3 weeks of driving like that will cost me the equivalent of a new sensor.

is that like a fibreglass washer?

What colour is the sensor probe when you take them out? If they are black, it may be that you are driving far too vigourously (ie RICH) and coating the sensor in carbon so it doesn't sense correctly.

Nup on the CES dumps the sensors are located downwards, I know a few people using them I think Adam (abo bob) has the same dump.

Tune is pretty conservative off-boost, on boost is static 12:1 AFR

if yours is Type A id say you've found the culprit

02 sensors are very pedantic about location, how they are mounted and temperature/pressure in the exhaust

so it could be pressure is too high (unlikely) or temp is too high (have you checked EGT?) - again unlikely in normal turbo applications

upside down is big no no, they will die a short death each time, its plastered all over the bosch install guide somewhere if you can find it

try searching for Bosch LSU install or google it, youll find it for wideband 02 but its the same dealy for narrow band

wow im surprised at that, upside down 02 sensor

no wonder you keep killing them....

get another dump pipe and it will be fine

what a shame hey, im surprised no one else has picked up on that or noticed?

who installed it?

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
