08 explorer sport trac
I have 08 sport trac, my fuel pump went bad and I replaced the pump I left out the valve that the pump first hooks up to,anyway I finished with tank and pump,the truck busted right off but I noticed the cel was on so I scan it and I get po 108 po453 po403 I drove it and started running rough,showed terrible gas mileage ,shifting was off,went home and scanned it again and now i have a po191 added to the other 3. Can the tank pressure sensor cause the 108,403,191 to affect the other 3 codes or whatever you good sirs think my problem is ,I'd appreciate whatever you think the problem is.
