Injector O rings?Slagburn said:Hmm. No, that cackle clip does not sound like this truck as the idle speed in the clip remains steady. This one fluctuates rpm by maybe +- 50 or so, enough to rock the truck slightly. The oil is changed routinely, the fluctuation happens whether hot or cold, and the truck runs fine otherwise.
Maybe I'll go ask over there. Thanks!
Cackle isn't an issue on '97 and older PSD's. They don't have the same injector system (splitshot) as the '99s and up.FYRMAN said:
