The symptoms you described, such as the tachometer moving up and down, the exhaust emitting black smoke, and the engine shaking and slowing down and speeding up by itself, could be caused by a variety of issues.
Here are a few things you can try:
Check the fuel system. A problem with the fuel system, such as a clogged fuel filter or a malfunctioning fuel pump, could cause the engine to run poorly and experience shaking and misfiring.
Check the ignition system. A problem with the ignition system, such as faulty spark plugs or a malfunctioning ignition coil, could cause the engine to run poorly and experience shaking and misfiring.
Check the engine oil level. Low engine oil level can cause the engine to run poorly and experience shaking.
Check the engine timing. If the engine timing is off, it can cause the engine to run poorly and experience shaking and misfiring.
If you are unable to identify the source of the problem or if the issue persists after checking these components, I recommend having a mechanic diagnose and repair the issue to ensure that the problem is properly addressed and the vehicle is safe to drive.
