sounds like avacuum leak to me, there should be a vacuum diagram on the under side of your hood. you need to check every thing in the diagram for leaks. the best way is to use a propane torch you do this by starting the motor the take the torch and open the gas valve ( DO NOT LIGHT THE TORCH then point the torch on all the lines and components if there is a leak any where the engines idle speed will change.
