Sticking at 2000 rpm and burning plasticic smell

[impactblue]

I was driving my freshly built car around my neighborhood and idle started sticking around 2000rpm and took a minute or so to low back down. Rushed to the driveway and shut it off and noticed some smoke. Looked to be coming from drivers side close to firewall

Freshly built as in freshly modified or freshly manufactured? What mods?

What could it be

Built motor. Heads. Cams headers. And 15% lower

I guess intake and Ford racing throttle body as well

I'd look for oil dripping on the headers or something else coming in contact with the header. I had a burning smell after I started mine and a paper towel had fallen between the header and the shock tower.

It's a very plastic/chemical smell. Like it smells like if you put your face in the smoke you would never see again lol

Are you sure you're headers aren't baking off any grease or oil that got on them from being handled? Did you do the idle learn process when you started it the first time?

I took apart the intake and throttle body. Couldn't find anything. Put it back together and it works now. Weird

Sounds to me if it is that "fresh" you were just burning off top layer of coatings\oil, god knows what else, esp if now it is not doing it...intake\tb wouldn't cause a burning smell..

You say the fire-wall, so was the smoke actually coming INSIDE the cabin or did you pop the hood and see the smoke from where the fire-wall is located?
