Rory Posted September 4, 2007 Share Posted September 4, 2007 I've just taken mine out this afternoon, dead easy all you need is a 12mm socket. Each sensor is held in by 2 bolts. Easy enough to get in at on my N/A, quick spray of WD40 and they came off no bother. They are now currently stuck into a fresh lemon, mmm tasty ! I'll leave them there over night.

Chris Wilson Posted September 4, 2007 Share Posted September 4, 2007 Why don't you just get them tested to see if they are OK or not? Link to comment Share on other sites More sharing options...
Rory Posted September 4, 2007 Share Posted September 4, 2007 How do you test them ? Plug in diagnostic computer? Link to comment Share on other sites More sharing options...

I'll leave them there over night. have no idea if theres any difference between N/A and TT but i found it a complete pain in the arse to get to. I ended up buying 2 extensions to the socket set (ended up about 2 foot long) and one of the thingies that allows you to go round bends...but as you can probably tell from my technical input i'm not particularly good under the bonnet.

Dazzi Posted September 4, 2007 Share Posted September 4, 2007 Did you attack it from above or below? Found it's easier if you get under the car. Link to comment Share on other sites More sharing options...
Nic Posted September 4, 2007 Share Posted September 4, 2007 Most Supras out there now, must still be running around on the factory fitted O2 sensor(s). If you have not changed your O2 sensor in the last 3 years, then it is probably well past it and running way to rich. Fitting a new O2 sensor will pay for itself in fuel saving in no time and your car will run a lot more smoothly at low rpms. Link to comment Share on other sites More sharing options...

Elmo Posted September 4, 2007 Share Posted September 4, 2007 Should start a pole to see if the lemon thing actually works. How many have cleaned their o2 sensors with a lemon and how many people noticed a marked improvement or vice versa? Link to comment Share on other sites More sharing options...

Dave Posted September 4, 2007 Share Posted September 4, 2007 just done mine 10 mins to remove overnite in a lemon mpg is a lot better and it runs better [smoother] up in the revs Link to comment Share on other sites More sharing options...
Jamesy Posted September 4, 2007 Share Posted September 4, 2007 i rang my local import specialst today to see if he could do this lemon thing for me and he advised me not to do it at all as it could screw up the engine messing about with the sensor - said its better just to buy a new one.... ... i am wet behind the ears to it all, but it seems to work fine for every1 else....and anything i can do to imorove MPG has to be a bonus!!!

Jspec Germany Posted September 4, 2007 Share Posted September 4, 2007 I'm actually considering this as a test. Maybe do a tank full on the autobahn at semi-fixed speed and measure mpg, then do it again post lemon spa-treatment. Meanwhile, think I'll PM Nic.

Of course it's best to buy a new one, but if you want a quick fix for a coked up oxy sensor, getting the cr*p off it does work. Link to comment Share on other sites More sharing options...

Rory Posted September 4, 2007 Share Posted September 4, 2007 I'll be refitting my freshly lemon-ised sensors tomorrow, so will take it a run to see how she goes and fill up the tank to test mpg and report back here. The lemon certainly does take the black carbon deposits off the sensors anyway, I have some pics to show difference , will stick them up tomorrow.

Homer Posted September 4, 2007 Share Posted September 4, 2007 thanx mate...just gotta find some one to help me do it now!! It's very, very easy to do on a TT mate. NA's are a bit more tricky though Link to comment Share on other sites More sharing options...
