welcome aboard.

if the engine is vibrating, you may need to check out your motor mounts. "rpm playing all the time" do you mean fluctuating?(sp?) if sdo, you may have a vaccum leak or may need to adjust the idle air control valve located at the rear of the intake manifold. (should just take a phillips head screwdriver) try those and let us know what you find.

OK I will do it , but what about the black smoke ?

[jltibbs]

change valve cover gaskets and seals, and run some seafoam, if you have that wherever you are, one half can in oil, one half can in fuel.

can you be more specific please ?
