Hello,
I am having a problem with my Bronco stalling when cold and while driving the freeway the power seems to sputter minimally. It usually stalls when I start the truck up and put it into gear. I recently had a refurbished engine installed but this problem was happening before and continues with the new engine. I have basically replaced everything on the engine with new parts from sparkplugs to a new EGR valve. I have taken it to a mechanis shop and they can not figure out why the engine would do this. I am thinking it is something electrical since it is EFI. Any advice would help since I have tried all I can think of.

The temp sending unit could be sending the wrong temp to the ECM causing it to mix the fuel wrong causing it to run improperly
