last week my freestar started running like shit all of a sudden. it idles rough but consistent and when taken for a drive and kicked down runs rough and takes forever to shift. rmps way higher to initiate a shift than before. im getting a code p0171. which from what i can see can be several causes. my initial thought was plugs or wires. changed the front three but having a hell of a time getting at the back three. the thing that is odd is that it never threatens to stall at all, just runs rough and consistently rough and started all at once. any help from the experts on here would be appreciated as im not keen on paying 129$\]hr at the dealer. heading out now to clean the maf sensor.
