    There is a good chance its a head gasket. The coolant in the combustion chamber is the problem though.

    My fault Its none of the above. Black smoke would be from a rich fuel mixture.

I dont know where do you live, but honda civic 1992 don use carburator, they are fuel injection, you can have coolant temp sensor problem, or map sensor problem, run diagnose jumping the diagnose wires loated in the passenger side, kick panell close to the door wall, better get the repair book in the parts store to locate the conector ,and read how you can run the diagnosis

SOURCE: f-150 4.9 lt .once it starts, blowing heavy black smoke

Sounds like its flooding(excess fuel)Try squeezing the main fuel line enough to allow enough fuel through for engine to run smoothly if that improves running of engine either fuel pump needs replacement or pressure relief valve has failed or has no vacuum to activate it.Dirty or failing injectors can also cause your problem,try putting a can/bottle of injector cleaner in fuel tank to see if it improves running of engine.Air flow meter can also be an issue.A few potential reasons foryour problem and too hard to lock it down to a single cause without the vehicle being in front of me to do the appropriate tests so have just provided the basic causes and hope your able to take it from here and solve the problem.Good luck

SOURCE: Cold start-extremely rough idle-Shakes,smell fuel

Black smoke means buring rich. Have the vehicle's ECU scanned for codes and do the repair the codes describe. I'm gonna take a stab in the dark and say Mass Air Flow Sensor.(MAF)

My honda civic shakes a little when I start it in the morning and then it's fine after a few minutes


DO YOU SEE YOUR HONDA CIVIC SMOKE AT THE TAIL PIPE, COULD IT BE THAT IT SMOKES WHITE.
HAVE YOU CHECKED YOUR COOLANT LEVEL,
IF YOU NEED COOLANT OR SMOKES WHITE, MEANS THAT COOLANT GET INTO THE CYLINDER HEAD CHAMBER. ALL IT NEEDS IS A SMALL AMOUNT TO MAKE IT SKIP.

The motor shakes in my 960 volvo sedan why could that be


A shaking engine usually is an indicator of an engine missfire. Secondary ignition components are the most common failure (Spark plugs, plug wires, etc..). Less likely, but still a consideration are the fuel system components such as the fuel injectors or filter. Further down the list with a vibration in gear at idle are bad engine mounts. If it worsens with engine load such as acceleration then it is likely the ignition system.
Good luck
