rumble in the revs

[dudehog]

hello again folks. ok here's my NEWEST problem.......
from a low rpm the car begins to vibrate. it is most noticable at 1800 - 2000 rpm.
after this is fades out through the revs.
i've checked the plugs and coils and made no difference.
it doe it in gear or out of gear. it feels like something is out of balance. any ideas........let me know. thanks. john

If you can get it to do it while you're under the hood (bonnet) use a mechanics stethoscope or a long screwdriver up against your ear. Touch the other end to things like the alt. pwr st. pump A/C compressor or anything that has rotating parts. At least you might be able to pinpoint where the noise is coming from. Just my $.02

problem found and fixed. although it doesn't show on the cars fault light thing, the problem was the oxygen sensor, or lambda. call it what you will. now it runs absolutely fine.
just keeping everyone updated. hope this helps someone out in the future.

Just curious, how did you determine which O2 sensor to replace? The OBDII cars over here in the new world have 4/$100+ each and light the check engine light when they fail. Or did you just scan it?

while it was in getting the clutch fixed they ran a scan on it and it showed up as that. fault code reset and now all is fine.
