I'm going to try cleaning mass air flow sensor and then check refrence V for o2 sensors,do you know what the ohms for either sensor should be?

I don’t think so. Idle air control and oxygen sensors won’t cause surging at both speeds. If you want us to check this out please call 313-562-7022 or schedule an appointment on line at StansGarage.net. I am sure we can diagnose it and give you the answer you need.
