Hi everyone, has anyone come across these error codes from the OBD2 scanner, once in awhile my engine stunbles usuall while waiting for a red light, the check engine light has come on and then goes off. found error code is P0171 System too lean (A/F) Bank 1 , secondary codes P)174 Bank 2. could this be from a dirty MAP/ MAF sensor, and where would it be located...Appreciate any advice and comments...
Thank You all

OK, problem solved , the Mass air flow sensor was right there in front of my noise by the air intake area, removed it cleaned it with sensor cleaner and error codes disappeared..
