Default TPI surging (?) idle

JUst started up the 383 over the weekend. Seems it doesn't want to hold a steady idle.If I adjust the AIC to idle at 800(its a 4 speed) it will idle fine then jump to 1050 for a short time then drop to 700 ect... Any idea where I should be looking. All sensors are new,no apparent vacum leaks, 7730 ecm

Default did you burn your own chip?

If you are, you can go here and make a copy of some other 730 bins to see if it cures your surging.
