I have a 99 gs eclipse. I've had an air/fuel gauge on it now for like 2 years. i really haven't payed MUCH attention to it for a while, which doesn't make any sense. BUT for some reason it goes really lean for a couple seconds, then really rich for a couple of seconds. And when i'm driving and let off the gas pedal it drops to lean and goes so low the light starts to disappear. Guess i'm just wanting to know if there is any tweaking i can do to make it more ideal. Even if i put new plugs, and wires on, it still does it. I don't have a wideband. Stock 02 sensor. any input would be great. Thanx

Its a peice of ****. It doesnt mean anything. Thats what happens when you buy a narrowband

Its doing its job. Though, you likely have little to no use for a wideband, as you have a 420a... Odds are whoever installed it, did it for show.
