Help ! Code reads P0171 !


Recommended Posts

Check engine light is on an the "cruise " light blinks. Any suggestions of what it could be and how to fix? Got a road trip coming up and i need my baby to be ready.

 

Car runs perfect to me. Cant feel any difference in performance

could you pull a learning view and post it here please? your air/fuel ratio is way off so you probably should take it easy until it is resolved.

 

one preliminary guess would be a big air leak like the turbo inlet hose torn where it connects to the turbo, but more info would help.
