My car hesitates like the fuel is being cut off when I drive any higher than 2k rpms.

-I have a new fuel pump
-It has the 12v hotwire mod

When i corner hard, It hesitates really bad, no matter what rpm.
Just took a look at the fuel pump and mounted it as low as possible; didnt fix it

Heres a video: http://www.youtube.com/watch?v=-KAOVJ0_Zd4

Now some testing after searching through some threads

-Checked The two main sensors connected to the intake manifold, they are not corroded and seem clipped on fine

-Disconnected the MAF
Car was really fast for about 2 min, then started bogging
Throttle response way still much better, With the MAF plugged in throttle seems laggy.

And lastly I am throwing code 71, egr malfunction, BUT.....

Ive had that code since Ive owned the car, and the car has been fine for over a year. Code will periodically turn on and off.

Worn engine mounts will cause the cars engine to move excessively when cornering making vacuum leaks in places such as the large hose connecting the brake booster to the engine. These instant leaks from the engine moving and tugging the vac lines makes problems.

ALSO, the second thing it does when the engine shifts and has worn engine mounts is lift the engine enough to move the ground and cause a floating ground which will attempt to stall the engine and make it run like azz.

Check mounts, check main ground WELL (inside the clamps) inspect hose going to brake booster by flexing it to check for cracks from being stretched.

Well i checked for potential vacuum leaks and couldnt find any.

Also, it seems the more fuel i fill the car up with, the less severe the problem is.

Is there a difference going up and down hills? What about the fuel filter?

i believe your egr valve is stuck open. try removing the vacuum line going to the top of the egr and see if that helps
