Had this happen before on an older system with 3512B's and Ross Hill system, couple of things you can check to verify the problem.
1. Hook up ET and check your throttle signal should be i believe at 1-3 at start up
2 If not and it is high compared to the other engines at start up you most likely have the following problem.
Inside your control panel you will find the PWM module and what is called a barrier module behind it, most likel the Barrier has gone bad and is allowing full battery voltage to your ECM during start up whick will cause a very high throttle signal.
easy fix is to change both the PWM and the barrier.
