Started the car up for the first time after being put away for the winter. Car is running great so I decided to test the alkycontrol system. Hit the test button and got no stumble. Kept hitting it, nothing. Drove around a bit and at every stop light, hit the button. Eventually I started to get a stumble after hitting the test button. Sound like the pump is on it's way out??
EDIT: I've had this installed for about 3 years now FYI
