sounds like lack of air past the throttle plates causing the ECU to try and fix the idle,,,,id suggest adjusting the idle speed control up a bit (located in the throttle body,,, some one may need to show u a picture of this,,,,or try do a search),, think this will fix your problem,,,,

It could be a problem with the Throttle Body adjustment, or it could be a problem with Idle Speed Control valve itself. It is most likely not a vacuum leak, as the stock ECU will compensate for this and correct the idle.
