Default 98 Sonoma 2.2L idling problem

New to forum, have idling problem after vehicle is warm, flutters from 900RPM to 800RPM. Replaced EGR, fuel filter, idle air and tps sensor. Tried Map sensor and returned. Replaced one vacuum hose.

Still flutters??? Thanks

you try testing for vacuum leaks with carb cleaner, spray around intake man and tb and other vacuum lines with the engine running and listen for pitch change
