From what it sounds like it is your Throttle Body Actuator. This causes the ASR and ABS light to come on. Have you replaced the harness in that car yet? It is a 93 so it will need one. Check the wires, especially the ones that go to the TBA. Do a search on TBA and you will find links on how to test and send them in for rebuild. It could be your Harness causing the TBA to fail, but a failing harness can damage the TBA too.
One thing that is of concern is the it sounds like you have some clicking relays too, the 93 has those goofy fuses, take each one out, inspect it, clean the ends, make sure you have no bad fuses as this will cause relay malfunction and can effect your engine controls as well.
Was the car running when you brought it home? You said you just let it sit and now this? You may have to spend some time on it, can you reach the prior owner to find out if the harness has been replaced? just curious, good luck!
