Vibrations?


PAG

Recommended Posts

Wondering what could cause this?When i have her in neutral and rise the revs to around 3000rpm and hold it there the engine has a steady pulsing sort of vibration(soz couldnt think of any other way to describe it)then after 3000rpm its fine?I haved owned the car for two years and have never changed the plugs or leads and whilst having a look through the service history couldnt see any reciepts for a previous plug change.Would this be a likley cause or should i be worried?

Is it the actual engine that is producing the noise, or could it be something else resonationing at a certain rpm, eg. a loose bolt, exhaust bracket, etc?

 

If you've not changed the plugs for 2 years change them, it may not be the cause of the problem, but would be well worth doing anyway.
