Got an 05 dodge 6 speed 140,000 miles replace injectors at 128,000(stock ones). Truck runs great but starting it up it'll throw a cloud of bluish white smoke? And had it today barely want to start blowing bluish whitish smoke? It has new rail pressure relief valve and valve cover wiring harness. Any ideas? Rpms also go from 550-850 when it's rolling to a stop is that normal? Please shed some light on the situation for me would really like to get this fixed ASAP. Thanks for any help y'all can provide.
