So i have a couple problems with me dirty 1st off when its real cold -5 or a random star ups she starts loping but it goes away after she warms up. No diesel in fuel had injector replaced 7k miles ago. Wat can it be ? FPR ? CP3?. 2nd problem is i have a leak coolant constant/dripp, she doesnt over heat or eat coolant. And has some pressure in the coolant REZ tank. Wat the hell?!

 

do a balance rate test on the injectors to see if any are out of spec when the truck is warmed up. with the injectors being replaced it makes me think that you have leaky injector sleeves causing your cooling system to pressurize causing your leak somewhere.
