Kurog, random rpm at stoplight during cold engine

Mga ka istoryanz, good am.

Pa advice kung unsa problema ani. If magbyahe ako like short km pa galing sa house namin then once mag s-stop ako either stop light or traffic, biglang mag jolts/kick ung car ko then ung RPM biglang mag random (vibration din; using A/C or not), from 400- 1k, then balik sa dati. Mostly na experience ko to during morning or ung galing pa sa cold engine..
Once makaka ilang km na ako like 20km+, mawawala na ung problem during mag s-stop, pero nakakatrauma

Honda fit surplus 2008 model
salamat - newbie lng po

DONE with TB cleaning - using carb cleaner. Changed new air filter.
New tranny - almost 1 yr used
Sabi ng erpats ko hinaloan daw ng maliit ung CVT fluid ko ng National brand ATF - makaka apekto ba yun?
Newly changed oil and filter (kaso exist pa din ung prob)

Check sparkplugs, MAF sensor, IAC valves and vacuum hoses.
