How do I know if I have a bad injector? Starts good, idles good, running 60-70 smooth, but when I hit the throttle feels like a spark plug miss, not huge just noticeable. 175,000 on injectors.

First, check your oil level and does it need to be changed? Do you have any of the popular diagnostic apps; ForScan, Torque Pro & etc..? You could do a cct and buzz test. You could also use Torque to check your HPOP pressure and IPR %. Another option would be to ohm out your harness at the IDM plug. Do the test procedure on this link.

Good luck and let us know. I'm sure more will chime in.
