I assume you are having a knock at idle, that goes away when you rev it up, is that correct?

Also, how many miles on it?

Did you replace your wiring harnesses and valve cover gaskets when you did the injectors?

I had the wiring harness under the valve covers fail almost immediately after changing injectors. I think flexing the insulation on wires that have that many miles is just too much for them.
Another thing to check is your oil level. Low oil might also cause your symptoms.
