Last week i started the flash up and heard-felt a loud vibration running threw the car.
I revved the car several times stood still, then the noise-vibe went?
This is a first, and not a wellcome noise.
Any ideas?
Cars a 964 c-2 1990 with 77,000.

fouled plug? Possible dodgy plug lead or dizzy cap? I'd do the obvious before thinking the worst :twisted:

Plug, lead?
Had new sets fitted last month, i dont think so.

It went worse-stronger when revved, the alternater has a bearing(fan allso has one).
Does anyone know te result of a fan bearing failing?
Does it make a strange violent vibe/noise? Its the only thing i can think of that is moveing whilst not movein :?
