Looking for the does and don't of repair/replacement of the IMRC from those who have done this before. Thanks in advance for any and all helpful replies to this post

New to this site I hope you fixed your problem? I've recently come upon the same problem will be working on my IMRcv friday hopefully I'll solve this its been a tough one won't pass smog runs great except at lower rpms slightly sputters just enough to give a high CO2 reading to fail it. So I either I replace the 1 bank IMRC with a used one from the junk yard or buy a new one. I've tried seafoam replaced the dpef valve,EGR valve, vaccum control breather valves almost anything that would cause the code 1537 and engine light still came back on as you might guess this has been costly mechanic fees and parts killing me I'll check to see if they can be opened up and cleaned keep you informed if you have any thing please hit me back.
