I think I am going to just run a wire from the back of the wiring harness to the ecu plug.....D3 is the plug i believe for the OBD1 ecus. I wonder why I never got an error code or anything. But also, my only other problem is the idle. It always sits at 1500RPM, and I know that isn't right. I thought it was the ground, but I got 2 new grounds, and it still sits too high. Could that have something to do with my IAT error code I get(code10)?

So my current problems are:

Knock Sensor wire
high Idle
IAT error code

Could these 3 in combination with each other cause my crappy times and poor performance?
