Default Video of my Zietronix...(trying to fix rich idle) help!!!

okay so i have been trying to figure out my rich idle and rich running conditions.
first off my car will run at 9.8 afr through every rpms and every amount of gas given.
sometime the afr on the zietronix will flutter in between numbers but is usually stuck at 9.8

now i am trying to figure out if there is something wrong with my zietronix or something else.
it seems almost the same thing happens when i just turn to accessory or if i start the car...take a look
here are two videos

video #1 = just turning the ignition on to accessory and watching zt2 gauge
http://www.youtube.com/watch?v=c7DwwliqmWw
video #2 = starting car and let idle for a minute
http://www.youtube.com/watch?v=OW0_rx-XJzI

if anyone has any insight it would help this car has not been running all summer and i would like to enjoy it before winter hits.

thanks

chris

o2 sensor might be shot, i know mine is and it is stuck at 14.9 all the time. I think there is some thing up with your wideband, your car wouldn't idle that nice at <10 on the AFR.

What rpm does it idle at? Does it sound like it's idling right? (hard to tell from the video)
When my car idled any richer than ~13:1 it started to want to die...

I think it would run like dirt at 9.8 afr throughout the rpms and the afr should certainly change with different levels of acceleration...

I'll check mine in the morning, but pretty sure it does not go rich like that with the engine off. looks to me like something is going on with your zeit. Might want to confirm wiring and grounds are all good. Did it just start doing this, or is this your initial installation of the wideband? I had to replace my sensor after a while, but when mine went bad, it would just act sluggish -- sticking on a number for too long -- but not going rich like that...
