Leans out at idle?????

**Max121** · 02-18-2009, 10:57 AM

I have a Auto Meter phantom Wideband car its showing that it leans out at idle under boost its fine just don't know what it's deal is. My check engine light came on to said low voltage in the Left O2 sensore.

It's cold and have had time to play with the car so I fig some help would be nice before I get working on it.

Thanks

well how much lean is it? if we are talking 15.5-16.0:1, i don't see that as an issue. if it's 18:1, that would explain the low voltage SES light. you would need to go into your PCM and add fuel.

Mrr23,
I am guess / hoping it's a fouled o2 sensor right now. My Yband is slugest reading when its working. I hate working on shit in the cold so I am going to wait till it get above freezing to try that...If that dosn't do it I am going to get a new tune on it....Winter blows were is this warm weather!!!!!!!!!!!!!!
