I have to have my 94 F150 emission tested next week. Scan shows the code PO 171 , lean left bank. What do I have to do to clear this code ? I have the straight 6 in my truck . Ironically, my 06 Freestyle is showing the same code . Thanks for any help.

 

check your fuel pressure?

run some cleaner through the tank?

 

Thanks for the reply. Truck passed e test even with the light on. So, just going to keep on truckin for the time being.
