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

It's gonna have plugs on coil for sure, a little more pricey than a cap, rotor and some wires. More so if it's a hemi and has the double plugs

I guess I was thinking its an older model from the 70's. OP didnt give the year.

You're correct if it's newer.

Hard to say without motor specifics, but he says a used one in similar condition would be 26k. That's 2010 or newer.
