ASSUMING you calibrated by using the hidden buttons l and C per op man... Did you 'wind up' the sensors before installation or were they factory assembled. You send 5 V down to the potentiometers and receive back about 1.5 to 4.3 V. If the brain doesn't receive this V reading or if it is on the verge it will shudder. Also sensitivity will effect this. Turn it down , however I doubt it will cure your problem.
