Acceleration Issues

After a inspection, took the car on the road and the EGR Valve Blew out with a hole in the side of it. I was also running on a Engine with a misfire. We fixed the misfire and also replaced the EGR Valve and the EGR solnoid. so when applying gas, the car gives little to no power, flooring it still gives about 20mph. Any idea what that may be?

Guess and I hope you fixed all the damage from this "blow-out" with a hole! If you drove that any significant time with a misfire you may have clogged up converters which would cause loss of power. For now I'd check for exhaust restriction,

If you don't know how to check for exhaust restrictions or excessive back pressure hit back. Just looking will mean nothing,

Couple ways but start with an easy one:
Put a "T" in a known actual intake manifold vacuum line. Hook that up to a vacuum gauge and unless very high altitude it should read about 18 +/- . Now hold idle (no load) at 2,000 and it should read the same as at idle. If not there's a restriction but doesn't tell you where. Converters are the most likely but you don't know for sure.
Another test is to loosen exhaust before converter(s) and go for a quick drive. Noisy, but if power is up to par again it seriously points to restriction.
Start with the first and see what you find,

PS: This is a fav tool of mine. Both a vacuum pump for testing things AND has stuff to put in lines with the gauge! Voila!

What do you think about these
P1400 Differential Pressure Feedback Electronic Sensor circuit Low Voltage P1401 Differential Pressure Feedback Electronic Sensor circuit High Voltage
Could any of these be the cause for the no acceleration?

That suggests what was suspected but know I'm retired and don't have the charts for what each code means nor exactly what it's trying to say. Post just those code #s like you just did under the section "Trouble Codes" or whatever we're calling it now,
