Something Broke ( gonna make more powerful 220hp coming up)

The secondary butterflies aren't involved in the idle system.

Are you sure about that? the end of the shaft has some interesting linkage on it that involves the primary butterfly shaft. If you just remove the plates it wouldn't be an issue, but the removing the entire shaft deletes that.....not that I've tried to set up idle control on a stand-alone without it or anything....

Pic for reference... it does share the shaft with the secondaries... though I couldn't in good faith tell you if the secondaries have any effect in that complicated looking spring fest.

The purple arrow points to the primary throttle shaft. The red arrow points to the secondary TPS which is on the end of the secondary throttle shaft.

the ecu commands the secondarys to a certain position as the secondaries open it works the secondary tps (ecu reads to comfirm)so the ecu checks the position of the shaft.
so if they are not hooked up together then most likely it will set a code for secondary tps and maybe a code for the secondary throttle actuator (motor).

I can't speak for the secondaries, but the idle stepper apparently only monitors current draw to the motor. I used a couple of resistors in place of my idle stepper motor and now it doesn't throw a code.
