mine had 133k miles on them and were fine. the as-found test had all 6 injectors with 2% of each other (or 98% to 100% of spec) no cleaning was needed as these values were right were they should be. Very happy with turn around.

Lake County Illinois. Anyone know where I can have my injectors cleaned around here. I've looked online to no avail. Thanks guys.
