O2 help

[56chevywagon]

Any help would be greatly appreciated. I have been logging and have noticed that whatever I do I am either extremely lean or extremely rich and then when I am rich, I try to add fuel to the few lean cells and all of the sudden...it's all lean. I am not going to post multiple logs...in fact, I just re-installed the factory radix tune and rehooked up my MAF sensor but I was looking at the O2 waves and they are really choppy and laggy...I am really thinkinh that my O2's are going bad. I did swap the 2 down strem and I when from rich to lean just with the swap. Here is the log with the factory radix tune w/ the MAF hooked up (it is still learnign in this log though).

Again, any help is appreciated.

Thanks,
Cody

Not sure what the problem is, looks good.

You need to post a series of logs and tunes so we can see what you are changing. Without this info, there is little help we can give.

My question is mainly about the occilation of the O2 readings on the cart. They seam to be really choppy and lazy at times and I'm not sure if that is a sign of the O2's going bad or not. I will try to post new logs once I start changing up the tune again.

They should be going nuts. They look slow around idle which is somewhat typical as long as they are still moving.

O2 looks normal to me. Did notice some KR when you punch it. You will want to get rid of that in time. Using a WB to determine if you are rich/lean?

No WB yet, Still trying to work with the stock O2's...I'm trying a few other things which seem to be working. I'll post up new info when I can.

Careful!!! Stock (narrow band) O2 sensors are only really accurate around stoich. "TRYING" to tune off stoich conditions without a wideband is only asking for trouble.
