Thanks for the suggestion. I haven't tried a stethoscrope and don't have one but will certainly try that route after inspecting the vaccuum pump and pulling the valve cover to inspect the cam lobes along with shooting some pics of the lobes for review. Thanks for the suggestion . . . do you suggest a certain stethoscope? I've read on other posts of pulling the injector and running the scope that way?

Had that on the "next up" list, since it seemed like the easiest to inspect and rule out. Glad to hear another feelsl like the VP could be the culprit.

Will try that after the VP if the VP internals seems to be working decently. Will report back tomorrow on the VP on here with some pics/video since I've never pulled one before. I've read a few threads to have a decent idea of what to look for in terms of problems.


One thing I noticed which is hard to discern from the video is the idling tends to rev up and now about 200-300 rpm (guessing since the tach isn't working). Would that be due to a bad vaccuum pump or should I assume I need to work on the IP?

Thanks for the suggestions.
