When i did my throttle actuator dealer wanted 6 hours i did it in an hour and half so if your going to have the dealer do it expect for $$$$ ill let u know in a week or so so far car is running flawless no issues for a week and half. Usually it dies twice a day

Isn't the ICV only about $200? The actuators are around $1k (per).

I have this issue also, it doesn’t happen too often but it has in the past multiple times and I’m sure it still will but, when I come to a stop, sometimes the idle will just bounce a lot, almost getting as low as 100 rpms and then bouncing back up to 1000, and then usually it just settles and idles normally or sometimes the rpms dip and it doesn’t bounce back up and just dies, now I’ve noticed this usually happen after I get gas, and I’m wondering if maybe it’s a fuel breather valve issue because I’ve heard that could be it and most likely is what it is, but it doesn’t happen all the time, and I also don’t throw any codes.

It won't throw codes. I replaced mine and it solved these exact symptoms. Not a difficult fix.
