Drove home OK with P0500, ABS, Er SS, Check engine light, and flashing cruise control.
Got home, cleared the codes and now it won't idle or rev past 4000rpms.
Ideas?

P0500 is a speed sensor code. You will need to access the ABS controller for an associated ABS trouble code to determine the source of the problem.

How did you clear the codes? If you pulled the battery cable, the car will need to re-learn idle settings, will probably stall a bit until the learning phase is complete. I don't know if there's an extra rev limit in effect while learning, never tried...

If you use the built-in code scanner, you can access the "C" (chassis) codes which will tell you which wheel speed sensor is giving you trouble. Sometimes they have issues with water or snowpack intrusion and just drying out is all it takes to fix it.

Generic OBDII scanners cannot access the C codes. You either have to use a specialty machine, the Subaru Select Monitor system, or the built-in reader.
