code pullers do nothing but give code numbers which never identify a bad part, just a failed system. a scan tool runs from 3000-5000 depending on accessories.
let a shop check it for you and give you a bid. expierence is the best problem solver as we have been to schools for this and work at it every day.
171,174 is most likely a lean running condition from a vacuum leak or maf sensor. it needs to be verified by a tech.
