Rough idle

I have a 09 accord 2.4 and I’m restoring it like new. No matter what I’ve replaced it idles hard but once it’s moving it’s smooth I can’t figure out why it’s idling hard <personal information removed -mod>

Appreciate your service, but you need to put your car problem in the question title.
You won't be getting a phone call, so please come back and check here for replies.You shouldn't post that publicly on the internet anyway.

Thanks.

that's usually caused by an intake vacuum leak, or fouled MAF sensor.
