Hey guys I got a quick question. When I started my car today my car shutoff real quick for some reason. And when I actually have to gas it then it would stay on? but if I try to start it without gasing it. My rpm gauge would just drop

I am led to believe that your engine is having trouble getting air at idle, because when you touched the throttle and open up the butterfly it gets better. It's possibly a really dirty IACV.
does it still do it or was this only the one time?

might need to check the tps also

Well this is the first time it have ever done it, you know when you first start your car in the morning, the car idles high right now. But when its warm and I try to start it. It happens.

That leads me to believe your FITV is working properly which allows the car to idle high, but when the engine is hot and the FITV closes it has to rely on the IACV and the IACV is too clogged to do it.

Thats what I think may be the problem.

So do you think I gotta replace the IAC sensor or can I clean it up a bit

Take it off clean it with throttle body cleaner. Make sure the screen filter is clean when you're done.
See if that helps.
