Off idle hesitation - solved

But sometimes just like California vs US federal, where US federal was a year or more behind implementing certain requirements, Canada was often a year or 2 further behind in some of their requirements vs the the same model built for use in the US. I remember several models (like F-M-J especially) where we were choked up with having to run 3 converters, and Canada cars still had none or maybe 1.
Or US cars having lean burn BS and Canada still having the standard 4 pin electronic ignition box on the same given year and model
