Hello, I replaced the distributor in my 1989 van. I got the rotor and distributor back to the original location that the old one was setting (It was as close as I could get it, maybe its a tooth off, I'm not sure.). the new distributor fixed the sluggish, hesitation etc., that I was having.
Now when I drive it makes kind of a rattling noise upon acceleration ( it sounds like I'm driving an old diesel Mercedes, if anyone understands what I'm talking about). When I place my hand on the distributor cap while accelerating I can feel a vibration (feels like the rotor is contacting the inside of the cap). When I manually turn the distributor by hand slightly, the noise/ vibration becomes more/ less pronounce. This only happens while driving not while in park or idle.
here is a video with the noise.
Thank you for any input.
