Burning rich high idle sputters on star and acceleration

My car has 280000 miles.
My car has a manual transmission.

Check the spark plugs and wires as they are not working properly. The spark plugs are not burning the fuel or the fuel injectors are leaking. A leaking fuel injector or failed spark plug or wire will cause the engine to sputter. If you need further assistance with your engine sputtering, then seek out a professional, such as one from Your Mechanic, to help you.
