1994 Lexus SC300 Question: Throttle Position Sensor?

I just replaced the mass air flow sensor which made my car run smooth...except when I give it just a little throttle. It chugs for a few seconds and dies. Also the shift points in the transmission are screwed up. Anyone know if the throttle position sensor could be the culprit?
