I bought the truck a few months ago. I have no servie records since i bought it from a dealer. I did a valve lash a few weeks ago and while i had the cover off tested the injector to see how the motors where doing. all of them where .5 ohms. I want to know if you think the injectors have ever been changed or is it possable to have .5 ohms with 139,000 mile on them. Just looking to see if and when i need to change them. No issue with them just want some feed back.

They may have been changed, but not from the dealer.
