Recently my car started to "pulse/surging" at around 2000 rpm under normal and less than normal acceleration. It felt like the engine was cutting out intermittently. I had my fuel pressure checked at 25 psi. I was pretty sure it was a fuel delivery problem so I replaced my fuel pump and the fuel pressure regulator (Red Armstrong XP and Accufab adjustable). I set the fuel pressure at 45 psi and went off for a test drive. The same problem occurred, right around 2000 rpm again. I'm at a loss and stuck on where to go or test from here. Any ideas? Thanks guys.
