i relocated my maf sensor to directly in front of the throttle body and now i am having problems with my truck running rich and throwing p0172 p0175 which is rich on bank 1 and 2 .Then p1133 which is insufficient switching on o2 sensor i am going to relocate a new iat sensor to where my maf sensor used to be but will the maf off of a 2000 4.3 truck work they have the same numbers and look the same.thanks

 

I always wanted to try this very same mod but worried about too much turbulence at the throttle body opening, I know the F bodies have this but it must be different in some way to account for the turbulence. I am just speculating so I hope somebody else chimes in for you. Good luck!!

 

well it works good with my nitrous set up but the difference between the fbody and ours is they have a seperate iat sensor upstream and thats the only thing i can think has changed.

 

someone from here told me that if you dont have a straight path to the maf, like on fbodys, that the maf will not work properly because the bend in the intake right before the maf causes too much turbulence or a problem with the air flow and the maf reads wrong. just what i heard
