So I'm having a problem with my 97' Celica GT. One day started it up and got a CEL along with a very low rough idle. I was getting a code that my IAC was bad so I popped the hood and discovered that the previous owner clipped one of the wires to the IAC plug (the one that makes it open) so I reattached it and my code went away. but now the car idles at 2000rpm when cold and 1300 when warm. Before any of this, it idled perfectly at 750. I've discovered if I plug the port in the throttle body that leads to the IAC, the idle drops down to almost perfect. For some reason, the IAC is sticking open and causing this issue. I've replaced it along with my plugs and wires, ECT sensor and my O2 sensors and I can't find any vacuum leaks. I'm stumped on why the ECU is holding it open. Any ideas on what could be causing this? I've looked around for hours and can't find someone who has the same issue as I do. Any help is appreciated.

I've tried adjusting it both ways with little effect.
