Basically slow deceleration when I let off the throttle for a second. Only happens when driving. Revving in neutral is fine

 

You "cleaned" IAC by disassembly/no cleaner?

 

Not by disassembly that time, I wasn't confident enough or had the tools to disassemble it. By "hit or miss" I probably got the "miss". However, today the "sticking" revs isn't that noticeable. It is a lot warmer outside compared to the past 2 days

 

Snake oil. Your engine cleans itself.
