Could the MAP sensor affect the IAC, or vice versa?

What is your question?

I replaced both IAC and MAP sensors 9 months ago, and am getting codes 32 and 35. Could one affect the other?

OBD1 DTC code 32 is related to EGR system - IF idling is really rough - it is very possible the EGR valve it stuck in open position. That will also affect IAC counts - as viewed on scan tool live data screen.
