ok guys.My son totaled my 90 f150 5.0 so i got a 95 f150 5.0 with bad motor and put the motor out 90 in 95. all went in very easy. had to change out distributors and e few other parts. but now it is idling rough and sounds like it is missing a little . it has new plugs,wires,rotor,& cap.when you warm it up and give it some gas it seems like it smooths out but still won't run. anybody got any suggestions?
