You may want to use an actual fuel pressure gauge when driving. you could have pressure but not volume.
With fuel trims going that positive, the computer is trying to add fuel. Either the fuel delivery is not there or
a vacuum leak is suspect. Have you tried searching for vacuum leaks? Try using water.
