I've done a search and have come up pretty much empty. For the last few days, when driving the Zed I've felt a very buzzy like vibration. Its hard to explain but when my arm is lying on the center console you can feel it and its enough to almost put my arm to sleep. Its the wierdest thing and very hard to describe. I can feel it on the shifter and also a bit on the steering wheel. It seems to amplify with increased engine rpm's. The car runs fine otherwise, good power etc. The only recent events, had a complete service with plug change, but that was a month ago and this seems to be within the last few days. I'm at a loss and just thought I'd throw it out for any ideas before I take into the dealer. I'm sure they'll tell me its all in my head.
