That is bucking and sputtering.
I have a 1990 Mercury Cougar 3.8 NA that is bucking and coughing at all speed and has a very rough idle only while in drive with black smoke coming out the exhaust. It has new head gaskets, water pump, alternator, and other misc. I need to figure out what is wrong cause im stuck at my sisters house and need to get home.

start with a compression test to verify the motor is good.
make sure the firing order is correct.
it could be a bad injector or vacuum leak as well.
