ok.......

here's the deal....again...for you who will listen now

you can stop the oscillation in less than ten minutes.

after the swap, pull the plug on the battery, drain caps by hitting brakes and turning on lights

plug in batt

start car AND LET IDLE FOR 10 MINUTES

you have to re-learn the iac sensor to the new throttle body...it is oscilating to learn the position of the iac motor....unless you have a vac leak somewhere.
