i brought a apexi auto timer it i have fitted it in my question is
i need to connect it to the o2/oxygen sensor i have routed the wired from the sensor to car one reads o.00/ground on my meter the other reads 5.07 volts, when connected the a/f and o2 on the timer read nothing will the voltage change as the car warms up, what does happen to the o2 sensor i gather it gets hot and it's reading changes but for what purpose

also what boost does a standard wagon run i belive it has the t04 turbo on it

 

another thread dig up, but really need some help with this.

mine is reading between 100 and 700mV. but it doesnt stop changing

 

What you're describing sounds like perfectly normal behaviour on a narrowband lambda sensor at idle. If you monitor it under boost the output should climb to 0.9 volts or so and stay there.

 

thanks a lot for your answer.

it all started because i cant get my tt to provide a "theoretical" (and unaccurate) afr value. it shows 14.6 and the led blinks between red and green (even after a drive). it might be a misconfiguration on the o2 sensor value, but i tried it several ways and got to no conclusion.

anyway, thanks a lot for your precious help. if you can come up with something, please let me know.
