I don't know how to upload a video or would.

Start car it sounds good and strong.

About a min in while parked the rpm is at 1000 idle..

Then it starts to go from 1k rpm to 1,100 rpm

It does this steady for a couple minutes then it goes..

From 1k to 1,000 rpm dips down to about 900 ... that is maybe a second to do that then stays like that consistently..

Should I be worried

Nice. The good thing about the Hemis is there's a huge community around them. I'd search youtube and forums.

I have a 5.7, should be similar. Your idle is definitely high, mine settles in around mid to high 600s. Get some carb, brake, throttlebody cleaner, whatever. spray it around the intake manifold. If you get a surge, you found(one of) your leak(s). Don't be too liberal with the shit though, there could be a vaccuum leak in a hose nearby. Or it could be your IAC valve or throttle body maybe isn't zero'd.

Mine hesitates to start sometimes, it's new to me and the previous owner was running nos, EGR delete, no air filter. Tons of hack shit. So I was going to go over the IAC valve and throttle body and see if anything is fucked up. I'll let you know if I find anything about the 6.1 IAC

Almost certainly a vacuum line
