Runs rough between 1500-2000

Hey guys looking for some info there is no codes and it only runs rough from 1500-2000. Oil change has been done and fuel filters have been done. Im guessing maybe an injector not spraying right if anyone has an idea i would appreciate some info thanks.

Injector copper o-ring leak. Test it by removing fuel lines from secondary fuel filter and cover the ends with balloons. Remove ficm relay to keep the injectors from firing. Check valves need to be out of the banjo bolts. Whatever side puffs up the ballon is the side that has a leak.

Thanks for the info PSDPlayer. Would i notice any other thing caused by injector o-ring going bad and is normal to not notice this at any other rpm thanks.
