new engine rough idle
hi i just put a new engine in my truck while i had transmission out the old engine had cylinder 2 low compression so i installed new engine transfered over my 8 month old stg 1 160 cc injectors truck runs amazing except at idle warm it has cylinder 4 and 5 contribution codes so i swapped injectors from 2 and 3 to see if it was a faulty injector 3 days later still the same issue pulled compression on all cylinders all are great ( should be with new engine ) n accordance to  pin point tests there is no electrical issue that can cause this but i call bs now why would it idle rough intermittently i have only 500km on new motor helppppp
