Topic: worrying vibration Posted: 29-December-2004 at 07:49 |
I had to move my car a couple of feet last weekend, and rather than
switching off after 5 seconds I let the engine run for about a minute, to avoid leaving it flooded. It idled fine at 500rpm. Just for fun, I leaned on the loud pedal a bit, taking the revs up to about 1500 - 2000rpm. It was then that I noticed an intermittant vibration through the car, lasting about one full second, and repeating after a full second each time. It disappeared at idle again. Is this a V8 characterisitc, or a symptom of something expensive? The engine was cold, and there is nothing noticeable when driving. Thanks. |

What happened to this did it ever go away?

Well I've been driving normally since then, including the odd thrash, and
everything has felt fine. I haven't repeated the driveway test, though, so I am assuming it's a V8 thing. (or else I'm in denial). |

It's probably the engine rocking on the mounts.I'm assuming it's a vibration you just feel rather than one you can hear too?

Nothing audible. |

Unless some knows better I would say it's just the torque of the engine rocking it when you blip the loud pedal.Pop the bonnet and do it and you'll see the lump moving.

It sounds like a misfire, does it still do it around 1000-1300 rpm?
