Hello and welcome! My name isCustomerand I can assist you with your question. This condition is caused by an air/vacuum leak or a bad mass air flow sensor. Start by opening the hood and listening for a hissing sound at idle indicating a vacuum leak. Look close by the intake and throttle body as well as any vacuum hoses or lines and fix or replace as needed. In addition, be sure to check the air intake snorkle for cracks or rips and be sure it is attached on eother end nice and snug as this can cause your idle/surging conditiona as well as preventing the engine from reving up. If all checks out good, replace the mass air flow sensor.
