my 4v had a vacuum leak at the egr gasket (it was torn) and behaved the same, ran like shit part throttle, drove great full throttle, and idled perfect. Drove me crazy until I found that when I was tearing the intake manifold off to check everything.

You may have to bite the bullet and take it into a shop unless you have or can borrow a fuel pressure gauge, but check fuel pressure under load. A weak fuel pump can show good fuel pressure at idle but will drop off under load and can cause the vehicle to sputter.
