It's typical! Your car isn't going to die or anything.

It should idle just as smooth cold or hot, if everything is right.
When was it last tuned up - NGK plugs, wires, cap, rotor, injectors cleaned?

Year, engine and miles might be helpful.

I would pull a couple of the spark plugs to see if they are worn and if they are the correct ones for your engine. The factory plugs and wires should still be good to 100k, but the PO may have stuck in some oddball plugs for reasons unknown. If the rought idle is worse in wet weather, that would suggest and ignition problem.
If the plugs are good then I would suggest a can of injector cleaner in the gas tank. Techron, Seafoam, BG44K are good ones.

Get the NGKs and get your money back on the Bosch +4s. Junk IMHO. Only Denso or NGK plugs should be going in your Accord.

Get new a new air filter, Seafoam, TB Cleaner, MAF Cleaner, fresh oil/filter and a new PCV, then follow the instructions below:

This should help your Accord smooth out a bit.

What is meant by Amsoil 25k? 25K intervals? I hope not! Regarding the plugs, take them back and say they didn't work for your vehicle. I can't see why they wouldn't as long as it is in the last 30-60 days. I'm not a big fan of aftermarket intakes, stay stock IMHO.

typical J series running rough cold, too tight exhaust valves.

I'd toss out the crapsoil. It's not tested OR approved for use in Hondas, much less any car. But that's another story entirely.

Dump the Bosch plugs, they are garbage. The NGK platinums easily last 105k, and usually have no issues during their entire lifespan.
