need help
 

as i started my car yesterday afternoon. it took for ever to start up and when it did it was ideling really bad, when it first turn over the rpm was at 4k and then it drop down to like 1400. when i gave it a little gas and let off my foot, it feel as if the car was about to die out.humm.

second thing, when i let my car idel there is alot of black smoke coming out of it( and i mean alot of black smoke), i think the car is running rich because i can smell alot of gas coming out of it.

right around now i can use any help.

thanks ahead of time.
