evinX Posted August 23, 2011 Share Posted August 23, 2011 (edited) Hi all, changed my exhaust temperature sensor yesterday, old bolts sheared of so drilled and tapped new bolts from toyota in, and used a new gasket from toyota. Today after a long drive i popped into the shops, when i came back and fired her up i noticed she was hunting at idle. Turned her of then back on and it stopped, could the sensor be the issue? didnt want to strip my new threads to tightened to a reasonable feel. Got any suggestions? She hasnt done it since. http://a6.sphotos.ak.fbcdn.net/hphotos-ak-ash4/320745_2334504038995_1141640031_4461187_1219150_n.jpg Kev Edited August 23, 2011 by evinX (see edit history) Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted August 23, 2011 Share Posted August 23, 2011 The Cat temp sensor wont effect the idle, its just there to notify you if your cat overheats. I would check your Spark plug clips... Quote Link to comment Share on other sites More sharing options...
evinX Posted August 23, 2011 Author Share Posted August 23, 2011 Not even if theres a slight gap leaking air or anything like that?? Quote Link to comment Share on other sites More sharing options...
JakeG Posted August 23, 2011 Share Posted August 23, 2011 Could of been a bit of bad petrol you put in Quote Link to comment Share on other sites More sharing options...
evinX Posted August 23, 2011 Author Share Posted August 23, 2011 My dad said that to, but since i tightened the bolts she hasnt done it since, bizzare. Was going to get some exhaust paste to seal around the sensor, becuase i changed it yesterday and this is the first time its ever done it!

evinX Posted August 23, 2011 Author Share Posted August 23, 2011 But then again when i fitted my back box, the old rusty bracket split leaving a big gap in the system and she never done it either...and my family memembers car packed in becuase she complained of the car being sluggish...and they live in the same area i get petrol from...BP! hmmm Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 24, 2011 Share Posted August 24, 2011 If you had an air leak there it's very close to the O2 sensor, so it could give a false reading. Quote Link to comment Share on other sites More sharing options...
evinX Posted August 25, 2011 Author Share Posted August 25, 2011 That was probably it, the bolts were a little loose so gave them a tight lock now, and sealed around the sensor with some gungum Quote Link to comment Share on other sites More sharing options...
evinX Posted August 28, 2011 Author Share Posted August 28, 2011 Bringing this back up as im not 100% happy with the seal, is there anything i can use like a gasket maker? thats hard wearing and heat resistant? only thing i can see hindering the seal are 2 rusty surfaces joining!
