Re: car exhaust smells little black smoke!
a bad iacv, or a clogged or dirty one, would not cause your car to have black smoke... it WOULD however cause your car to idle very jumpy, or rough. Could cause it to bog as well. There are 2 bolts, take those out, 2 hose, take those off, clean it with carb cleaner, let it dry, very lightly lube it with silicon or wd40... put it back on, see what happens.
Before u do that, battery... b4 u do anything electrical pull ur battery.
but if you say it blows black smoke in neutral sometimes, and sometimes its fine... i doubt it is internals in your block or head... especially when it will be fine sometimes and not, do a run down of your car.

Re: car exhaust smells little black smoke!
alright got it checked by a mechanic the car is not leaking gas and the car runs fine no power loss he said it not burning the gas right i have a gas like odor smell he and a little gas in my oil he said u might have a bad injector because i just change my spark plugs two days ago and they are already black and smell like gas he said to just run that way and see if i have any problems like power loss and shaking cuz the injector might just be going out what u guys think hes right or might be something else??

Re: car exhaust smells little black smoke!
black smoke could mean your running rich aswell, is your catalyic converter functional or are you running straight pipings

Re: car exhaust smells little black smoke!
You obviously are running too rich if you are smelling unburnt fuel, What is your ecu chipped for? You most likely need to get it tuned.
