Im currently getting a slight power loss while driving and hesitation on taking off also idles a little funky. went out bought a used dizzy from someone and getting the same exact problem. timing seems okay havent taken the cover off but cam lobes line up at tdc and so does crank pulley now im unsure any insight?

my thoughts on possible reason but unsure if they'd cause code 11?
coolant temp sensor
fuel pump

Hey and welcome to NICO Club! The best thing to diagnose codes is a FSM, typically the EC chapter. Check the links on this page... not sure what car you have but code 11 is typically dizzy... could be weak battery, bad wires, bad grounds. Not sure about coolant and fuel.
