Very high Long fuel trims bank 1 & 2


Topic starter

I have a 2004 Dodge Ram 1500 with a 5.7 Hemi and auto trans 175000 miles with brand new rebuilt 9.25 w/  3.92's. cold air intake brand new injectors new EGR valve new throttle body gasket and freshly cleaned throttle body new coil packs. My long-term fuel trims have been stuck at 32.8 before and after all the new parts I was on my way home one day and the truck through a code open circuit injector one cylinder one took the harness off ohmed out all injectors. They all were to 12.4 but had really bad misfire and power loss from 1100 to 1500 RPMs then it would even out. Deleted the open circuit code then had lean code Bank 1 and Bank 2 hence  for the new injectors and EGR valve truck now runs great now but even after PCM and ecm reset long fuel trims are still stuck at 32.8 short-term trims are were they're supposed to be between negative -10 and +10. Have checked for vacuum leaks fuel pressure is at 60psi. What is causing these pegged long-term fuel trims?
