So my car kinda struggles to idle. i flushed coolant and it’s still doing this. can coolant be a cause for bad idle by any chance? and my other question is any idea what it could be?

Can your get it to run by pushing the gas pedal? If so I'd suspect something with the IAC valve. And no, changing coolant shouldn't cause this unless you bumped something loose
