Running Rough after TC Replacement

1997 F150 4.6 Triton, 2wd

A couple weeks ago I dropped the transmission out of my truck for the first time in order to replace the torque converter that has been giving me trouble for awhile. Put it all back together and started it.
It started fine but the engine immediately was running extremely rough and loud, almost like it wasn't firing correctly. It then began to smell of gas and really strong exhaust, almost like you were at a raceway. My tuner showed me that the coolant temperature went from completely cool to 170 from just idling and giving very little gas. Also a white smoke began to come from the engine compartment and that's when I shut her down.
I'm at a loss right now because the truck goes into gear fine and the exhaust is on tight. I'm hoping someone could shed some light as to why this is happening, thanks.

Check all of your electrical connections that you might have disturbed, very carefully. Along with any vacuum hoses too.
