racing engine

While trying to solve the gas smell problem I posted earlier, I think I may have done something. I removed the manifold,the air filter, the throttle and maybe a couple other things. I thought I got everything plugged backin but now the engine is racing whenI start up, it will come back down but still is idling way high. I drove it to autozone and they said it read code P0443. Can anyone help? Its a 2000 caravan with e 3 liter engine. Thanks.

Never mind. Fixed it. It was a vacuum thing
