If you have a diagnostic scan tool, you can run a buzz test and a cylinder contribution test.

If no scanner you can unplug one injector at a time while running and listen to the engine change sound. When there is no change in sound that is a bad injector.
Do all 8 you could have more than 1.

:agree: In addition, the cylinder contribution balance will show injectors that are weak that you may not hear or feel yet. It would always be a good idea to get the test done if you find a bad one the old-fashion way. It saves on the labour charge going back in the second or third time.:taze:
