Have you inspected the car's wiring harness?? If the wires are cracked, then it needs to be changed.

How is the altenator and battery?? Should be around 14+ volts with car running. Check battery for bad cell. Should be 12.5 volts w/ ingnition off after doing a battery test; cold cranking amps.

Obvious things: Base Module has four fuses; doubt that they are blown but if so then that would cause the roughness in your car. Never have seen them blown personally but . . . The base module is like the infamous "OVP" relay.

Wheel sensors next . .

The SRS codes are probably separate 'events' and those should be reset with a scanner. They may not come back. That's why I mentioned checking the altenator/battery. A low battery can cause a lot of problems.

But I still think the ETA is going (gone) bad . . .
