My engine on my F22B2 accord has a upper knock around 2500rpms and vibrates around 3k to 3.25k rpms then revs fine. At first I thought its was a wrist pin going bad but it revs fine. Or thought it was a connecting rod. Upon future looking into it I think it might be a bad valve. The engine idles fine for now. It also starts fine in the morning and will climb a hill just fine. Any ideas? It started vibrating about 2 days ago.

 

You could have an injector starting to play games. They can often make noise sometimes confused as a valve train noise (a light 'ticking'" noise). It could (conceivably) be causing a fuel delivery problem as well, thus the 'miss'.

Actually, the best way to work through this is to road test the vehicle and try duplicating the condition.
If I heard it, I'd probaly take almost no time figuring it out; but if you want to do it this way - you're going to have to be more precise in your description.

I'll make a recording of it and post it, if I can, It will take a few days. I also intend to do a compression test. Once the engine is warm it makes this noise all the time at the rev band described. If I power brake the engine no noise is present. It only makes it when I rev it at idle or when taking off slowly. I drove it up a hill to see it load made it show it self. But at 3k the motor vibrates. So I either go 65 or 80. It hates 70.

 

I'm going to check the resistance of the injectors.
