Hey all just had a quick question. I just installed a new o2 sensor yesterday and put in some gauges (o2and egt) my question is that the air/fuel gauge is stuck lit in the green (rich) as soon as i turn on the car. drive it and still the same. O2 readings are at 0.0 when at idle on my logger but when i go for a drive the o2 starts to cycle but the air fuel stays the same.
so basicly
air/fuel does not move from rich
O2 trim at idle is at 0.0
what could be wrong any help would be appreciated
Thanks in advance...
 
You might already know this, but an A/F gauge is almost totally useless on the stock narrow band O2 sensor. Its pretty much a pretty gauge with lights unless you get a wide band O2.
 
this i do know but thats the thing i only can see one light green and that is all. one green lil light...
 
So unless i have a wideband sensor, an A/F gauge is not very accurate? would the EGT be a better investment? What is rich/stoic/lean on a EGT gauge.
