no issue before the swap aside from the trans slipping.. I kept the US ECU.. I swaped over the intake and all the lovely emmissions stuff.. I also recently replaced the Fuel VSV sensors on top of the engine.. I have a friend that is ASE cert.. once it makes temp the voltage at the temp sensor maf and 02 sensors is correct.. so I am pretty much down to a vacuum leak somewhere or maybe the cold start sensor..? I have so much time and money tied up into this I would really like to get it squared away..
