Recheck your work, maybe you knocked something loose, somewhere.

Can you check for codes? If you have a 16 pin data link connector, your probably obd11. You'd need an obd11 code reader or scanner.

Is the throttle valve closed all the way?

You might unplug the tps then start the engine, see if it effects the idle, if it does, you might check the sensor circuits, ref voltage--ground--signal.
