Hello, I'm back. The ABS module was rebuilt and installed on the car. The ABS light is still on, unfortunately. I got to drive it around for about 5 minutes before I had to go to work and the shaking wasn't present, but every time I disconnect my battery cable for a while the shaking stops for a bit. I will keep y'all updated as I'm installing the motor mounts this weekend. Main reason for the post is this question. The ABS light is still there and I'm fairly certain the shaking has not gone away. Should I buy the vacuum pump or a vacuum gauge? I don't know if there are many more points of failure for the ABS other than the pump.
