So I was about to pull codes when the engine was running and when I connected the jumper from the sti to the other harness, the idle began to creep up more and more. Any idea what would cause this? Or any suggestions to what to do about it?
If I remember correctly, the engine speed does increase for one of the tests. I know that it will go to 1400-1500 RPM. It has been a while, so I am not sure about ever seeing it go above that.
