help with smoke when cold

OK so I got a 97 7.3 with 130,000 miles.the past 20k miles its been Smoking blue when cold and has a little bit of a miss to it when its cold until it gets to operating temperature and doesn't have quiet the power it use to have and doesn't get as good mpg..and when its 40°f or under out it WILL NOT start unless the block warmer is plugged in overnight..the mods on the truck are new stock turbo straight pipeed super chip so its pretty much stock the truck does not burn any oil at all..and when I say it smokes when cold its not just a little bit of smoke but it looks like a Forrest fire is happing in my neighborhood lol. Thanks for any help just curious on what to replace guessing all new injectors and glowplugs? Could it be just glowplugs?

Start with glow plugs or possibly just the glowplug relay and get the italian motorcraft ones autolites tend to detonate the tips on the cylinder. Loss of power mpg could be winter fuel. If new gps or relay dont help. Do the injector orings. The injectors dont tend to die very often. . To check gp relay as soon as you turn key on the volt meter should pull down hard. Whenever i buy a obs first things i do is gp relay glowplugs and injector orings.
