2006 Mercury Grand Marquis LS /P0106 Code

What is your question?

I have a 2006 Mercury Grand Marquis LS and experiencing rough idle and P0106 code. Initially changed EGR valve. No fix. Cleaned throttle body, Changed MAS Sensor, Throttle position sensor, Fuel injector pressure sensor, smoke test and changed red cluster of vacuum tubes because one was chewed through. I've been shotguning parts at this thing and a mechanic suggested changing the PCM /ECM. Did that. No fix. Back to square one. The P0106 code is pointing back to the MAP/Bio sensor. I believe this year model doesn't have a stand alone MAP/Bio sensor, it's incorporated in the EGR valve.

What makes this problem better or worse?

When driving I feel the vehicle sputtering
