Car turns on but no power of acceleration after intake manifold gasket change

I recently changed my intake manifold gasket on my car after a p0171 code. When I was removing my manifold a coolant tube on the throttle body came loose and leaked so I decided to flush the engine coolant out and refill. After putting everything back into place I cranked the car and it would turn on and quickly idle hard and shut off. I went to check the hood and the gasket was out of place. I bought another gasket and redid the process. I put everything back into place properly plus clipped some chipped tube that connected to the manifold. When I turned the car on it idled rough but stayed on and ran. However, when it came time to move it I hit the gas and it had no power whatsoever. I’m not sure if I did something wrong here.
