Hesitation/studder with these codes . .. . . .. .

[reags8]

OK got the intake back on right and the vacuum lines routed correctly with the secondaries opening right and the studder/hesitation which I intially was attempting to fix is worse. I pulled the following codes :
172 - Oxygen sensor not switching - system is or was lean - Single Right or Rear HO2S
176 - Oxygen sensor not switching - system is or was lean Left or Front HO2S
177 - Oxygen sensor not switching - system was rich Left or Front HO2S
332 - EGR did not open/respond during test or if memory code did not open intermittantly
543 - Fuel pump monitor circuit shows no power (Service 556 code first if present) Fuel pump relay or battery power feed was open
When I get into the car hard it reacts well but when I try to cruise and just touch the pedal in 4th it studders and bucks.
Also when I throw it into park the tach jumps to 1300 rpms then stalls.
Any help ?
I've replaced the DPFE should I replace the EGR ?

You've still got a vacuum leak.

OK then where to start ?
I just ordered new intake gaskets, egr valve gasket and will swap out all the vacuum lines that I can get to.
Any other suggestions ?
