has anyone swapped a later model motor into there chassis, I swapped and 08 into mine and i cant get rid of the p0174 code. I have checked for vac leaks, swapped maf, intakes and replaced gaskets, o2 sensors, cats, replaced coils, done a fuel injector leak test, the bank one trim is good where the bank two lttrim is out at 30%, I've been hitting a brick wall and cant get around it. I asked my ? on that just answer site and the guy claims the cams are diffrent and is what is causing the problem? seems like it would do it on both sides.
Any ideas?

 

Did you swap the computer? Could there be a difference in the computer between a 04 and a 08 ?

 

no the chassis i bought didnt have the pcm with it he took that when he swapped the body

 

figured Id finally put the answer out there in case someone else comes along... Pcm and wiring harness were the same had a plugged catalytic converter
