Rough idle

Hey! So my e30 is running rough on idle (up and down between about 700 to 1500 rpm)
I was thinking of grabbing some throttle body cleaner to try and clear it up, is this wise? Or maybe look for a new ICV?
Any help appreciated

it would be helpful to us if you could let us know which engine the car has.

It is almost always air leaks on the induction side.

What Ben said, check the basics like splits in the intake bellows but easiest way is to get a smoke leak test done.
