Injector diagnosis questions...

My '93 W350 idles VERY smoothly, in gear or in Neutral"...What could be the reason that a '91 Non-IC (our CTD RC) would idle "rougher" under the same circumstances? I'm sure there are MANY reasons, but the one that I'm concerned with, is injectors. Specifically, having a "bad" one in "Red" (the '91). It is running great, but at what expense? Is there a way to tell if an injector is going or is Bad, without removing them? I want to pull them and get them checked, but funds are shallow at the moment. I don't think that is what I'm dealing with, but I'd like and idea of what to listen or watch for. Any opinions?

Thanks,
Andrew
