1987 300 SDL

Hello enthusiasts! I have just purchased a 1987 300 SDL. I am very excited about this, especially since it is my first car.
The good:
$2,300 black paint job (says the seller, I didn't see any receipts)
New brakes, calipers, brake lines
New headlights
Newer tires
No rust (was a Georgia car)
It flys when you kick it to the floor...
Trap Oxidizer was replaced, along with the airbag, in 1997

The bad:
Front ball joints needed replacing, he gave me two brand new ball joints and im having them put it
Windshield is cracked
Sunroof doesn't open, he gave me another sun roof to install myself
Engine has a loud idle/knocking sound

I got it for 1,300 bucks, so im pretty happy.

Heres my question: What do you think is causing the loud idle? When I get it past 1500/2000 rpm it purrs, but when its below that there is a definite knocking sound. Also, accelerating produces some black smoke. My uncle who is a mechanic says that it could be a faulty fuel injector...would that make sense?
