The car is chugging and also blowing out dark smoke

Destroy your radiator, drain all the oil, and redline this piece of junk

Smoke diagnostic is made by colour.
If u mean pistons head gasket,yes,it can smoke.
White (clear) water vapor.Ceck coolant level.Ceck engine oil colour by dipstick.

Black:runs rech on fuel (fuel filter/fuel lines/fuel mixture...)
Blue (whity):worn pistons rings.

Chears.
Tips:
Whity smoke before warming may be natural on cilli mornings with lot of compressure the engines just blows vapors.
Old oil/fuel residues in the exhaust tubing may blow smoke after heating the engine ,must track problem (...).
Black smoke on hitting the acceleration to the floor may be natural (overcharged) avoid sport driving style.

check spark plugs and wires.

there is moisture going inside the distributor cap ,probably has a hair line crack ..i would just change the cap and rotor button good luck

THis could be several things. Start by making sure that there is nothing under the hood that is hitting the belts or pulleys. Check the oil level. If the oil level is low, add enough to top it off according to the dipstick. If the oil is okay, look to see if it is dark, thin and runny. If so, change it and the filter. If that is all okay, it could be a valve or lifter. Watch for oily spots to show up on the rear bumper which would indicate that you are blowing oil out the bottom of the engine - not a good thing. Also watch for smoke coming out the tailpipe after the car is hot - don't confuse steam in the early morning's cool air with smoke.

get it serviced my friend sound like your about to blow if you dont

Try having someone else start the vehicle in a dark place while you look at the motor compartment. It sounds like a shorting out electrical problem. You might be able to see fire shorting to the engine block in the dark.

the valve seals in the motor are worn and letting oil seep into the cylinders when the vehicle sets overnight. when you start it in the morning it burns off the collected oil.. have oil seals replaced if you are parcial to your car....

mine also smokes at 2000rpm and only at 2000rpm when i left my car for a couple of weeks it would not start too bat was good was just yurning over and popping?????????? please helppppp

with only that little bit of info., i'll guess at spark plugs and a mass airflow sensor. is the engine lite on? what color is the smoke? maybe even coolant temp switch.
