Have you also cracked the fuel delivery lines one at at time to each injector while the engine is idling and note it's characteristics? You should notice a harsher idle. If you crack one and no change, then it's time to do an injector/cylinder swap and retest to rule out bad injector.

Did you also check the operations of the engine shocks? I have seen them look ok visually, but had no resistance when actually moved. The engine shocks should be pretty stiff to move.

Glad to here the mounts are good.
