A 4.3L V6 engine may exhibit symptoms of running on only four cylinders due to issues such as a faulty spark plug, ignition coil, or fuel injector that can cause misfiring or poor combustion. Additionally, vacuum leaks, low compression in one or more cylinders, or problems with the engine's fuel delivery system can also contribute to this issue. Diagnosing the exact cause typically involves checking the ignition and fuel systems, as well as performing a compression test on the cylinders.

1995 astro van 43L CFI Why do the right 3 cylinders load -up smoke and foul plugs?
Several possabilities. One is a bad PCV valve if it leads to that bank of cyl. Another is the intake gasket for that side of the engine. Worst case, but not likely as it is affecting all of the cyl, is a failed head gasket. One question, are the plugs fouling with fuel or oil? If over fueling, it could also be an injector or injector wireing issue. Could it also be bad oxygen sensors? If there are four oxygen sensors on this van, and the one for the right bank of cylinders is giving the wrong reading, that could cause this problem. Seems unlikely, though.
