Good Evening fellow enthusiasts! Still trying to get the kinks out of my 1997 Ranger xlt so far have replaced mass air flow sensor, performed tune up (autolite plugs and duralast wires) both EGR tubes and valve have been replaced and all vacuum hoses checked over. now check engine light is on with codes P0172 and P0175. Only diffence in performance I notice is when I first start driving there is a lot of smoke exiting tailpipe then it starts to go away when warmed up other than that fuel mileage seems decent and idle is smooth. Where should I start?
