Has anyone out there done the R2.8 conversion in their TJ?

Found out that it wasn’t the fuel gelling.

In a lapse of dealing with broken bolts of the rear shocks. I never put lube in the rear differential during the Dana 44 swap.

So The Jeep was stalling because the rear bearings were seized.
 
It's been close to 70F here lately. Coldest I've started that engine was about 8F. My truck aftermarket fuel system has coolant ports and heater port thing I think.
