Rough / low idle only once engine is hot (after about 20 mins of driving) (1 Viewer)

[hbange97]

FZJ80 manual starts and runs perfectly from cold. After about 20mins it will idle pretty rough when I pull up to a stop. Also start to get a stronger fuel smell from the exhaust..

Vacuum pipes are all clear so thinking maybe an O2 sensor from what ive read online. Thoughts?

I would look at the IAC valve and VSV based on what I see there.
