I know this is an old thread but I thought I would resolve it as I had the issue myself and found no answer on the forums.
If you hear a loud ticking from the TB area and you have trac mounted to the throttle body, there is a good chance that your traction pot is out of alignment. If the part is not broken it is an easy fix.
TO diagnose that this is your ticking, disconnect the cable a the rear of the TB, not the 2 o n the pots, the one connected towards the cabin, just above the plastic airflow assembly.
Set the ignition to on and see if the ticking is gone. If it is, you need to realign the trac pot
