Thread: Rumble at idle with occasional popping sound

I was just saying the 3800 coils in general, not just the Autozone ones. Sounds like new plugs are on the agenda for tomorrow. Thanks!

So, changed out the plugs and wires tonight...no luck. No change in the sound, although I don't think I heard any popping. The rumble didn't change at all though. Any suggestions? I think tomorrow i'm going to try running it with no belts to see if it goes away. I know my power steering pump is on it's last leg.
