clarky666 Posted June 3, 2010 Share Posted June 3, 2010 (edited) Just thought i would post this as i'd been humming and hawwing over the last couple of months regarding this. Running a completely standard N/A auto setup other than an aftermarket air filter and my fuel economy has been getting poorer since i put the Supra back on the road after the harsh winter we had. Initially thought it was a combination of fuel prices hiking up but i'd started being a bit more methodical and nothing down how much juice i was putting in and resetting my counter each time i filled up. Was getting to the stage where i was down to around 80-ish miles off £20 and you could see it was over fuelling whilst standing behind the car even if it was warmed up to normal temp sitting at idle and getting a very potent whiff of the fumes. Got the car serviced yesterday and decided to swap out the o2 sensors on her whilst i was at it (thanks to Keron for those). Made sure she only had enough petrol to get her to the garage, took her for a run after it and put in another £20 and after a spirited motorway drive back to my flat then another couple of trips on slower rural roads to the golf course and back i'm sitting at around 120 miles on the clock and not even hitting the orange warning light yet. That is one hell of a difference to be fair. Wish i had acted earlier now !! I know this aint a shoe-in fix for the over fuelling / poor economy but it definitely is worth considering sooner rather than later if having similar problems especially the way petrol prices are going.

Nic Posted June 3, 2010 Share Posted June 3, 2010 getting to the point where i need a full service on my n/a. i will put one of these on the list of things to be done. Thanks for the tip. You'll need to put 2 on the list. NA - 2 x O2 sensors J-Spec TT - 1 x O2 sensor UK TT - 2 x O2 sensors The oxygen sensors are not cheap, around the price of a tank of fuel each, but they should quickly pay for themselves in fuel savings. The car should also feel more lively at low rpms. Quote Link to comment Share on other sites More sharing options...
kill1308 Posted June 3, 2010 Share Posted June 3, 2010 My fuel economy also went up dramatically when I replaced the O2 sensor on my TT. I was getting 190-200 miles a tank in the end, when I replaced the sensor I can get 270ish now! Quote Link to comment Share on other sites More sharing options...
Supra N_A Posted June 3, 2010 Share Posted June 3, 2010 how much are these NA - 2 x O2 sensors get them from toyota?? Quote Link to comment Share on other sites More sharing options...
kill1308 Posted June 3, 2010 Share Posted June 3, 2010 how much are these NA - 2 x O2 sensors get them from toyota?? No idea what they'd be for a NA sorry, I bought a genuine Toyota one though, I've heard bad things about generic ones, but don't take my word for it. I'd imagine Whifbitz or someone like that would be able to source you one? Quote Link to comment Share on other sites More sharing options...

Neil-NA Posted June 3, 2010 Share Posted June 3, 2010 I could do with replacing mine, getting around 60 miles to £20 and there is alot of popping when backing of and changing gear. Mine is an NA so if anyone gets a price please post up. Quote Link to comment Share on other sites More sharing options...
clarky666 Posted June 3, 2010 Author Share Posted June 3, 2010 Toyota were something daft like £125 + VAT if i recall correctly, which was bad enough before i realised i needed two for the N/A as i think one is before the cat and one after. I managed to get two from Keron try him before wasting your dosh on Toyota. Quote Link to comment Share on other sites More sharing options...
aman00123 Posted June 3, 2010 Share Posted June 3, 2010 Nice one, thanks for the info Question, are the lambda sensors from companies from the web alright? If so, they seem to be a hell of a lot cheaper than what we're talking about on here..... Not sure if I'm allowed to post links to other websites, so if I can't can a mod please take the link off please? These guys have them new for around £60 http://www.autogateway.co.uk/NewCategory--ExhaustLambdaValveSensor-110.25# Quote Link to comment Share on other sites More sharing options...
