If the vehicle emits black heavy smoke, the fault will likely to be from the injector pump....
The economy problem is first attend to by replacing the fuel filter.....Once removed, before fitting a replacement, fill it to the top with clean diesel fuel and then screw it home....Bleed all remaining air and when starting the engine, bleed the individual injectors.....After completing also replace the air filter....

SOURCE: VTEC 1.8 135K. Starts OK
My experience has been when the car runs badly when cold and it runs well when it warms up, it is usually an O2 sensor. The sensor has a heater on it so that the computer gets a good signal when the engine is not up to temperature.

check to make sure the crank sensor is no knoed out of place or cracked. Could also be intake leak. Famous for that also
