If you are running a factory ECU the only thing you can do is reset it.

It is determined electronically. Throttle cable will not work.

To reset, make sure you have the radio code and disconnect the battery for a few seconds. You can do it by pulling a fuse also.

Yes.

One minute is more than enough.

The cable is not the problem. There is built in slack in the cable, do not remove it.

once you pull the fuse there is also an idle relearn procedure that you should follow. i do not know the procedure off of the relearn but im sure some searching would yield some results.
