Sounds like a vacuum leak. this will affect the idle causing it to idle high but with no power (at idle) so almost dies at idle in drive, (under resistance) The knocking is likely your exhaust pipe shaking and hitting under car, cos of the engine shake.
Look for a vacuum tube hanging loose from around the intake area. Maybe trim off stretched end and reattach. May be able to hear it with engine running.

If the ABS light is on, there is a problem in the ABS system that the computer has detected. Unfortunately, you need an ABS code reader to find out what the issue is. Could be as simple as a wheel sensor, or something more complex. I would take it to a repair shop that you trust and have them retrieve the ABS code(s). that way you can properly fix it. Disconnecting the battery for 15 minutes will make the ABS light go off, but if the problem hasn't been fixed it will come back on.

Chances are that you don't have any tail lights either. They are both on the same circuit. Check your fuses. Most likely that one is blown. It's probably marked Dash/Tail or Tail Lghts. or something similar.
