.01 was enough to actuate and flutter the solenoid bank for the egr on my truck. As wella s throwing the mixture off. The ecm thought it os off-idle so time to open the EGR... didnt make for a good running truck...

The procedure I came across a while back was to disconnect the IAC and set the base idle @550-650 rpm that way, and then revisit the TPS voltage. Should put you in the neighborhood.
