Question Idle shake

I have noticed that my truck will kinda shake when at idle, not hard but subtle. Almost like a miss or stumble?
Seems to be more noticible now (4000 miles) then when new. RPM's dont change, at least on the stock gauge. Truck runs fine otherwise.
Normal?

Mine has always done the same thing, both my old truck(1500HD) and the one I have now.

Yeah, my '03 did it too but this one was smoother until recent. What do you think causes it?

my camaro had a nice shake on idle, just because it's a big engine. ran fine.

I bet if you had some softer motor mounts you wouldn't notice it as much. If you're concerned you can always go check the error codes and cylinder compressions.

My SS did it noticably before tuning. With some idle tuning you can get rid of a lot of it.

We have the same engine and i also have the little shake i though it was because of block we had or compression or something different but guess not.

Could it be slight variation in fuel injectors?
