I seen somewhere that when there is black sot it means the car is running rich what all could make the car run rich?

 

I have the same issue, mine is from leaking valve stems/seals.

does it smoke after sitting for a while?

 

Are you running an aftermarket intake or exhaust? If you have a large diameter intake and filter ( not the intake manifold) you could be throwing the MAP sensor off, and the ECU will respond by injecting more fuel, and then you get a rich mixture.


Maybe, but I don't know what you are running.

 

I really dont know when it smokes i'm guess it smokes when i get on it, i also am leaking oil from my dipstick tube towards the bottom its a pain in the *** i just put new a new crank seal, and cam seal so i was just down in there and everything was fine but i had that tube out and now its leaking

 

i have a exhaust and intake i think my intake is 3.5 or 4 inchs i have a air to fuel gauge and it says rich could i maybe need a new map sensor. My car also cuts out sometime i'll be on the gas then it just falls right on its face but still stays running if i flip the key it stops

If you step on the gas and see black smoke spewing out, yes, the car is running rich. If your looking in the exhaust tip and there's some black powder, sorry, its a byproduct of combustion as engineers haven't figured out how to get internal combustion engines to run completely soot free.
