Check Engine Light

Hope someone can help me w/this. Problem started after smogging the car. RPM's will drop to zero while I'm driving the car around, a few seconds later the check engine light goes on. It only lasts 10 - 15 seconds then the rpms jump back up to about 2200 and the check engine light goes off. The car runs fine while all this is going on but it just seems to happen more often. When I watch the tach while this is going on it justs drops to zero and stays there. When the tach comes back on where it's supposed to be it does not go back gradually but pegs out to normal. Hope it's a loose connection but where do I look?
