I've been running logs for about a week now with the 02 sensor reading just fine. Idle would be somewhere around 14.7. Well today after a couple days of not messing with it, I turned it on to find that the readings were acting up. I got 20's for idle and the numbers jumping between 20 and 100 and what not. Well I did the free air calibration but it is still acting up. Anyone know whats wrong?

 

bump

 

could be the sensor is dirty or the sensor is bad...i used to have the same problem i bought a new sensor and never happened again

 

ill try cleaning it. thanks

 

yea no problem also if anything clean the sensor and free air calib it then if that dont work its most likely the sensor or check out their chat forums....if im not mistaken its tuneyourengine.com
