Question The light on my 99 taurus is coming on with codes po171 po172. I changed the maf sensor but still have the same problem. running rough intermittently with light back on.
Answer hey there if i remember correctly these are codes indicating the engine is running lean. that indicates that there is a vacuum leak some where, chack all major vacuum lines and connections, and thene check for a possible intake leak. let me know what happens. good luck
Chris
