i swapped my IM out for a y8 one this weekend, it seemed to go pretty smoothly even though since i was using only a bare manifold i had to fabricate a lot of parts (ie a bracket to hold the throttle cable, iacv electrical hookup, drill into bottom plate, relocate IAT sensor, run a T for a coolant line, etc...) but when i start it up, only problem i'm getting is i'm running really rich, and missing a little. A/F sensor is reading the last green LED (way rich), and not only does it smell rich but it is smoking real bad, filling my garage w/ white smoke. what would cause it to run rich like this w/ only a new intake manifold? is the smoking related to having a cleaned-out manifold w/ no carbon or oil deposits? i'm hoping resetting the ECU will help a little, what else should i try? i just can't understand how a new IM would make it run richer...

I did relocate the IAT sensor (back bottom right of the b7 IM looking from front of car, a white plug w/ a white probe sticking out of it). i drilled into my CAI and plugged it here using the original gasket and RTV sealant- the liquid gasket stuff. i know for a fact it isn't leaking, but could the new reading be different than the way the original sensor would read (since now it's b4 the throttle body instead of after it)?

 

Im doing the same swap, did you ever solve your problem?
