Check the throttle body sensors and also clean the throttle body with a good throttle body cleaner. https://www.google.com/url? sa=t&source=web&rct=j&url=http://m.youtube.com/watch%3Fv %3DZ- vmUkR2TZA&ved=0ahUKEwjgvYz77afJAhWBRBoKHTsXA6cQt wIILzAA&usg=AFQjCNGi_768Oc3Q6_RjFE-cUZsehLIZyg

Also check the oxygen sensors and check for a clogged catalytic converter..

Sounds like a faulty MAP sensor. If check engine light is on, have codes read. Pull a couple of plugs. If really black or very white in color, that will indicate a faulty MAP sensor. It will cause your engine to burn too rich or lean. Will also cause your engine to surge and you will have terrible gas mileage.
