Scottish Storm Posted May 4, 2015 Report Share Posted May 4, 2015 If you've got a sensor on the way out, O2 for example, the car will keep reading the weird codes for a wee while before it goes "aye, sod this for a game of soldiers" Check any codes first would be my advice and if your lambda is more than ten years old it's probably not a bad time to replace it anyway.

Spelling errors caused by me not giving a toss After talking to a few people ur would point to the lambda. I'm not getting any error codes but it could be just working within it's range but not well. Think it might be worth me changing it as the car has done 85k now and 13 years old. Edited May 4, 2015 by cipprio Link to comment Share on other sites More sharing options...
Scottish Storm Posted May 4, 2015 Report Share Posted May 4, 2015 Mines has been okay but I swapped it out last week as the tuner saw it was a but sluggish. Margaret's TF though would run for a while then when the fuel trims were too far out it would start to play up. With her car I disconnected it and put the car into some programme where it just averaged out values and it ran better until I swapped it. Not a clue if that would work on a Celica though.

cipprio Posted May 5, 2015 Author Report Share Posted May 5, 2015 Think I'll just order a new one it won't do any harm and will rule out if it's the lambda that's causing problems. I still keep remembering back to my mot when on the emissions it only just came in a few seconds from the end of the test. Link to comment Share on other sites More sharing options...
cipprio Posted May 5, 2015 Author Report Share Posted May 5, 2015 The question now is what o2 sensor do I go for. They range from £40 -£60. Does this reflect in quality as the denso seem to be the most expensive. Link to comment Share on other sites More sharing options...
toiletduck Posted May 5, 2015 Report Share Posted May 5, 2015 I remember AMS (I think) saying there's no point in skimping on sensors since they last so long - best to go Denso or similar "proper" brand. Hopefully that's not too paraphrased, he was talking about lambdas but I assume same applies. Link to comment Share on other sites More sharing options...

Thats a lot of work that sensor has to do over the years. Link to comment Share on other sites More sharing options...

Looking at an engine conversion next year but at the moment the 140 seems pretty solid except for this little fueling problem. Link to comment Share on other sites More sharing options...
cipprio Posted May 11, 2015 Author Report Share Posted May 11, 2015 Left work this evening and the engine ran great. It's was 19 degrees out when I started the engine. This morning it ran rough and was only about 6. I think the problem is when the engines cold and the outside temp is down the ecu etc tells the engine to rich. It's so bad that putting my foot down in 3rd at about 3000rpm the car just lacks any power and takes a lifetime to get to around 6000rpm. Link to comment Share on other sites More sharing options...
