iac stepper testing ms2

[glowryder]

MsI have ms2 stepper controller wired in. I have my iastart set at 100 steps. When I turn. Key to run bu tnot cranking the pintle goes out (this would be no bypass air) and then retracts to 100 steps. This makes sence. But every time I turn to run and no crank the iac does this..but every time it seems to go out further and further ..eventually it pops apart..what gives?

I tried to run iac test in tuner studio and it doesn't do much..maybe I'm doing something wrong? If it were not wired right I would think when I turn to run no crank it would not go out and back.. so that teller me it can go out ( to 0 which is no bypass air) and to 100 which should be open..help!!
