There is no such thing as 4 people "equally" running a company, even if the equity is equally split, precisely to avoid these types of situations. If a majority of you (or whatever your charter says) are unhappy with the CEO, then you can change the CEO, but until then, someone needs to ultimately make decisions. Who do the two of you report to? Who is in charge? That person needs to figure this out. I'd also ask everyone in the room: What's in the best interest of the business?
