'95 Tahoe idles up and down

The truck will idle from 800 to 1100 at various times. Hot or cold but usually in the first hour of driving. I’ve cleaned the TBI and r&r’d the gasket and IAC. I’ve also did the starting fluid trick around the intake on both sides with no idle change. Also, driving is fine with no surging or issues. Any help is appreciated.
