      I will go out on a limb here and suggest that you have a vacuum leak, most likely the main seals. You can do a pressure test on the engine, but of cause that would assume you have the equipment to do that, or you could buy new seals and see if that makes a difference. Also check the intake rubber boot to see if there are any cracks.
