Limp Mode Issue, Need advise

[fixkick]

Well that does confirm my thought in that one of the POs did change out the ECMs as the hood is 58B01 and the ECM is 58B90..

So with that being said, is my only choice to find an ECM that is 58B30 or less since the hood does not say cali anywhere on it that I could find.

Or is there a way to wire in a resistor to fix the current one?

58B90
IS CALIF, 94 AND  FOR SURE IS IAT SENSOR ECU.  (the wrong ECU is known seen)
SEEN IN MY PDF ABOVE. that P/n.

Sure the resistor fix is easy,  or real IAT added  wired back to ECU

2400 to 2700  resistor should work. OF ANY KIND.
