Default Odd Boost Readings

I was cruising somewhere between 75-80 , keeping my speed steady, and I felt the gas kinda give way a little bit, and the boost went from -5 to 0. It was only for a split second, but it happened 2 times in succession. I just kept driving and it was fine all the way home(about 10 mins away from home on the expressway). I noticed the service engine soon light came on about 5 mins before this occured. Any thoughts?

Indeed...

The boost gauge acts as a vacuum gauge when you're not actually under boost, and the fact that it was showing you an occasional loss of vacuum makes me think that there'* some occasional clog somewhere that'* sending your backpressure way up. Loose debris in the catalytic convertor, maybe?
