Ok I replaced my orings on my crossovertubes lastnight an today while driving my truck I turned my comp to 5x5 an smartys on 8. In 5th gear at 1800rpm truck sputters or misses just a bit. Fuel pressure is normal about 16-17psi truck wasn't doing this before I replaced the orings. Could it be just air in the line or is something up with my truck? Only codes I have is fueling calabration error normal with non stock ecm an a compainion code im not sure the numbers but if it makes a difference I can plug my smarty in an getem (or key cycle) thanks for reading
