Received codes 132, 135 and 138. Replaced both O2 sensors and 10 Amp fuse. Car still runs rough at low rpms and engine light came back on with same codes?

Those codes rarely result from sensor problems. Instead, they refer to the entire circuit. Look for a wire harness that has fallen down onto hot exhaust parts. The wires could be melted together or they could be grounding out. Also check for corrosion between the pins in the electrical connectors.
