AFR ERRATIC. ANY THOUGHT?

I can't figure out how to post a video...
But;
After re-wiring the AFR away from the Tach signal, same problem.
I did talk to Wide-Band and they believe my power is not clean enough and recommended installing a 3300mfd 50v capacitor between the +12vdc and ground wire. I ordered one up (2 for $3.89 on Ebuy) should be here Friday and we will see what happens.
Getting irritating at this point. Wish I would have spent the extra $40 and got the Innovate or been told about this in the beginning. I noticed they have this info on their website now. It wasn't when I started with this issue.
Until the caps come in, I will power the AFR with a spare battery and see if it will give proper readings then. No alternator / dirty power then.

Can't speak to dirty power. Not sure what that means. You either have 12v or you don't.

To post a video, the easiest thing to do would be to upload it to youtube and then share the link. If you don't have a youtube account, send me a pm and I send you my email and can host it for you.
