When shifting the Gear into 'D' - Drive, the engine takes a minute to go at normal speed when the gas is pressed, it seems the engine hesitates to run.

Secondly, Sometimes when the gas is pressed a little stronger on Turns the engine will stall and shuts down, but it can be restarted, and also when the engine started in the morning there are unusual vibrations and little revolutions even w/o pressing the gas and there is a unusual black smoke coming from the muffler.

I've already replaced the Map Sensor, Spark Plugs and the Tension Wires and newly changed oil as well.

Please advise.

Thanks in advance.
