I recently replaced the EGR Valve. Now when I step on the accellerator, it doesn't seem to be getting the gas. The car will barely move when I step on the gas.

ok i replaced the egr valve, plugs, the springs in the coils, upper and lower manifold gasket, most of the hoses that show any wear, fuel filter, air filter, TPS, and it starts fine. When I slow the car down or accelerate hard the engine shutters and stutters and feels like its going to stall but then i ease off the gas it stops doing that....what am i missing to make it stop doing that? ok i replaced the egr valve, plugs, the springs in the coils, upper and lower manifold gasket, most of the hoses that show any wear, fuel filter, air filter, TPS, and it starts fine.

Hello, Try plugging the EGR Vacuum line again temporarily and see if that makes anything change. If that takes out the problem it can be a Programming problem as much as a EGR Solenoid. The PCM is rewritable and can be Reflashed, there may be updates for driveability. This Acceleration shudder reminds me of a bad spark advance which in the old cars would mean the engine is not advancing the spark. Now camshaft sensors are used.

You might call Advance autoparts first for checking the Camshaft sensor, as I understand they can check Modules and other parts the other major chains can't. Call around for sure. Your original suspicion was a fuel problem. With a rapid swing in acceleration, the fuel pressure Regulator must respond. There is a test spout on the fuelrail, you may find a loaner fuel pressure gauge to verify your operating pressure. Fordexpert
