prehung replacement door - wont shut

I have installed two prehung doors one for my back door and one for my basement. For some reason the back door wont shut unless you really press to shut it. It seems to bounce back from when it is almost closed. The basement door shuts no problem. Same doors, same frame type. I haven't any idea what i did wrong. any suggestions on how to give the back door more swing?
thanks

Just out of the box here. Sounds like you could have the hinge side not in line. This would try and keep the door from closeing. Id reshim the hinge side. When its in line the door should shut.

For me, it just took a lot of trial and error with different arrangements of the shims. I'd put a screw in the top, then the bottom was out. Had to back the screw back out of the top, reshim, etc. It also seems that working with the side opposite the problem is sometimes helpful.... Also, make sure the frame is not being pressed in anyway when just sitting in the opening without shims.

 

It sounds to me, that your door is hinge bound. Remove any shims other than those at the top and bottom on the hinge side, make sure that your jamb is in the opening squarely. gently close the door, watching the hinges for any deflection. If there is deflection and it is in the direction of the door closing, then your jamb is not square and must be shimmed at the inside edge, moving the hinge in the direction of the strike side of the jamb, proportionately for all hinges.
If at any time your efforts are impeded by the exterior molding, remove it, it can be reinstalled later.

 

Wood shims are tapered thats a good thing because most framing is not true.
Shimming between door jamb and studs should equal the air space in the rough opening that is seen on both side of the door jamb ( inside room and outside room) Meaning if you only see 1/4 inch day-lite on the inside of the room and 5/8 day-lite outside of the room your shimming should be the same.If you shim to much or to little you put a bind on your hinge ( you should be shimming directly behind your hinges )

Sounds like you put a bind on your hinges, re-shimming is in order here.
