With the engine running and loping, loosen (just a little, so as to leak enough fuel for the injector to not hit), one at a time, each high pressure fuel feed-line at the injector.
- If the lope goes to MUCH worse, that injector is OK.
- Move to the next injector, if the lope does not change . . . .. . DING!
But wait, swap that injector with a neighboring known good injector.
- If the suspect injector still presents as it did in the first test above, then sure enough, it's that injector.
- If nothing changed, as in, that same cylinder that didn't change, with loosening the fuel line doesn't change the lope, then, it's NOT an injector issue, it's something with that particular feed-line and/or its associated supply.
Make sense?
