O2 sensor replacement


danch

Recommended Posts

Hi guys,

My 99 Legacy threw me a engine check light for knock sensor and o2 sensor.

When idling, it sometimes feels like it\'s gonna stall - rpm varies very little tho. Between 900~700rpm.

I believe replacing o2 sensor could help with this problem?

I\'m slowly getting into the DIY world so thought I might do it myself- hopefully it\'s not too difficult.

I went to Repco and they charge about $250 for a new o2 sensor.

Would this be a feasible option? or would I be able to get something cheaper?

Thanks in advance for any advice.

Got a pic of the sensor? Ive got a genuine on coming off my V5 which Im damn sure is the same as upgrading to Wideband. Its genuine and done less then 5000km I just need to check the invoice against the odometer. Fitted by Wingers.

$100 will own it.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
