Car is spitting out black powder through muffler

Many possibles. Bad crank/cam sensor, EGR, coil/module, coolant temp sensor, clogged cat converter or muffler, incorrect fuel pressure.

Sound like you may have a catalytic converter plugging up. Take it to a muffler shop and have them check it for you.

It sounds like you have a hole somewhere in your exhaust. More than likely your muffler. I would recommend replacing it. You would have to cut out your existing muffler and clamp on a new one. You could also take it to an exhaust shop and get a new one put on (the easier one). Hope this helps! Please rate 4 thumbs up!

have a muffler shop check the exhust for a plugged cat, also could be the mas air flow meter. or really any number of things. the good thing is this is an OBD2 car and autozone should be able to pull codes from the reader port under the dash. i would probly start there then try the muffler shop.

this is carbon from the burning of gas and the reaction in the catalytic converter, unless it blows black all the time don't worry about it it is normal..

It sounds like your head may even be cracked....

bring the car to an exhast shop and have the exhaust system flow tested it could be your muffler came apart on the inside and is plugin the tail pipe

first of all , i would say check your oil pressure.second i would take a look at your oil pan and the screw that holds it together.because some times they put them on too tight scripping them,that can make it do most of the things you described above.or if its not tight enough,it could do the same. i hope i was helpful in some way. good luck

I would take it to a shop and have some general routine maintence done on it fluids, filters, spark plugs, etc.

It is out of timing perhaps the timing belt has slipped. There use to be a way to advance timing but the year of your car is done by computer so leads me to believe the timing belt.
