    NGK Wideband just counts down over and over

    Soooooo, I have an NGK wideband and I have had it installed for a few years. I have changed the sensor a few times and have just recently changed it again. After the install everything worked as it should. But recently it will count down from 20 a few times and then read 8.8.8.8, then show my AFR and then count down a few more times. Anyone have any similar issues?

    That's either a poor power supply or poor ground.

    I was thinking that myself but just couldn't find it. I will look harder. Thank you!
