About 3 weeks ago my check engine light came on 95 2.3L Ranger. l purchase a OBD2 code reader. l pluged in the code reader and it said 1443 is a Evaporative Emission Control System Control Valve. l replaced the valve and the light went off. About a week later my light came on again with the same 1443 code. l also replaced the valcum lines and the PCV valve. Anyone have any ideas???
