My temp constantly fluctuates, my air/fuel ratio constantly fluctuates too. Engine has 179k and has a new MAF, and just about every sensor known to man. has a complete msd ignition, etc. Ideas?

I would suspect computer problem.

 

Did you change the O2 sensor? That would cause the fluctuation in the Air/Fuel reading if it were bad. Other than that, maybe the ECM is going south?

 

o2 sensor probably has.. o... 6k on it. I replaced it december last year and didnt drive the car for at least 4 months.

Yes, This is a common problem with dodges "where most of my experiance is with computer problems" The ecm will filcker between cold start and warm run or just totaly think the A/F is lean and start pumping gas down it like crazy.
Try to get an ECM that is complete. One that came from an exact twin so to speak so you dont have to reuse any of your old computer parts. This should eleminate your problems.
