Ford Expedition error codes P0171 P0175 P0191
HELP.... at first I thought it Trans was going. had not get up and go just starting out or at high speed. Trans is fine. The mechanic had these error codes and said it may be the fuel pump driver module??? Has anyone experienced this or do you have any info on it. The part is a 2-3 week backorder. So i would think it has some problems...thanks everyone
