Re: Codes 171 & 174 TSB # 03-16-1 update
I did the Isolator bolts back in Nov 2007. Windstar 2000. Had 54K miles then. Now I have 90K on it. Got the dreaded two codes again P0171/174. If I clear the codes and they come back again in about two days or 50 miles.
My question is that has anyone got the codes again after the the job was done already? or could it be something else?.....thanks.
