Welcome, I'm Chris (aka Moose). I normally log in after 3 pm central. Please make sure to let me know exactly what is needed from me so I can provide EXCELLENT 5 STAR service. 0171 means the bank one side of the engine. The side of the engine with cylinder 1 is running lean. Very possible bank 2 0174 will soon follow. When an engine is running its getting fuel and oxygen. The upper O2 sensors are measuring the amount of oxygen in the exhaust. This tells the computer if more fuel or less fuel is needed, because there is a set amount of oxygen and fuel that is wasted and not used. Lean means there is to much oxygen in the exhaust. Possible causes for this are:intake vacuum leakEGR system issuesdirty MAF issuesmisfireweak sparkvalve concernsexhaust leakbad O2 sensorThe most common is a vacuum leak. The MAF sensor after the air filter tells the computer how much air is getting into the engine. Any air sucked into the intake which is under a vacuum would be not metered air. So use flammable brake cleaner and spray short bursts around all vacuum lines, intake gaskets. If a leak is sprayed the rpms will increase as this extra fuel is sucked into the intake and burnt off in the cylinder. -------------------------------------------------------------------------------------On your screen at the top you should see a rating 1-5 stars and a green submit button. Please make sure to select one and press submit. I am not compensated by the website unless a customer rates. Rating only pays me from the deposit you have already made, it does not charge you more, nor close the post. Also all follow ups are free and welcome.Thanks Chris
