the right way to clear the engine codes is with a scantool and if the car is stalling it will hurt the car in the long run with you don't get this fix

Have used scan tool to delete codes and truck is running good but lean codes keep coming back on. Isthis normal after installing an air intake system?

Are the codes P0171 & P0174. If so you have a vac leak at a rubber elbow in the PCV system. If you want more help e-mail at firstname.lastname@example.org
