Fitech idleing issues

Ok my problem came back but does it intermittently now around town but on a long drive the idle starts hanging to where I have to throttle the throttle quickly in order to get out of a some what cruise control which it happened before but went away. Thought the throttle was getting stuck since the tps showed 5% open when I let off so checked that at a stop and throttle is fine so idk what's going on there. Might have to relearn something or fiddle around the AFR closed loop rate but the loop rate in idle control I don't have that feature. Is there something I have to turn on and then it comes up or did I get an early unit that's SOL on that?
