I have been throwing a rich/lean code on my o2 sensor for the past month or so. Ill have the code removed and run it for bout 15 mile and the code comes back. is is possible that a wideband could fix this issue with my o2 sensor or should i look into tuning or both. Also any recomendations on a wideband o2 sensor?

 

Whats the code number? Stock sensors are narrowband (0-1 v), so it's probably not a sensor problem, it's just the sensor detects the problems. Hard to say without a code.

 

Either way a wideband wont correct a problem, it is strictly for carshows and tuning.

 

Only way to get rid of that code is get a tune. Talk to trifecta tuning

 

The codes P0171 and P0128 came up. P0128 has been fixed any suggestions for P0171?
