I have replaced my kitchen counter top and sink, The new drain is in a different position. The drain down pipe does not run into the "p" trap at a straight vertical, no matter what I do with the other elbows and pipes it is just not able to connect properly and maintain a straight vertical. I am temporarily using a flex down pipe, its not at all a permanent solution.
What can I do?

Sounds like you need to install a new P-trap. Cut it off past the trap and then re-plumb in the correct spot. You may be able to use the old P-trap depending on where you need to cut, how it's glued, etc, but without a picture that's impossible to judge.
Be sure when you cut it that you'll be able to get a new fitting on the end, that usually means at least 3/4" pipe sticking out into the cabinet space.
Dry fit the entire assembly first, including the tailpiece to the sink, and only glue it once it's all in place.
There are P-traps with unions on one end that can help if the fit is tight, and regular unions (or slipnuts) are also sometimes necessary.
