ugy Donating Members 199 Member For: 19y 2m 5d Location: Auckland Posted 09/01/10 10:49 PM Share Posted 09/01/10 10:49 PM (edited) Hi guys, I have an annoying vibration when I am idling, but as soon as I rev the engine it goes away. I also have the same problem when I am cruising but as soon as I accelerate over the 100ks on a private road it goes away also.I am leaning towards the exhaust but have had a look underneath and can't see it hitting anywhere.Would appreciate any suggestions on what it may be so I can check it out.

Getting a new clutch in a few weeks see if it goes away. Maybe check the heat shielding around the exhaust they are prone to rattle Link to comment Share on other sites More sharing options...
ugy Donating Members 199 Member For: 19y 2m 5d Location: Auckland Posted 10/01/10 07:28 AM Author Share Posted 10/01/10 07:28 AM (edited) It's an auto. I have a pit in the garage and have been under the car when it was idling and had my hand on the engine cross member and gearbox cross member and no vibration on them at all. Soon as I put my hand on the engine I can feel a vibration which transfers to the body of the car. I would think if it was a busted mount on the engine or gear box you would feel it through the cross member. Also there is no rattle or noise just a vibration.

Should be near 2000rpm off the top of my head. That may narrow the search down a bit, ie isolate the engine.Is the vibration the same when cruising as when idleing (if that's how you spell it)?I know mine has a erattic idle and stalls very rarely. (its hard to explain things in words/text when your describing noise/vibration etc)Just thinking if the vibration is in driveline or in wheels/suspension does your steering wheel vibrate?

berzerker Donating Members 767 Member For: 17y 5d Gender: Male Location: Brisbane Posted 10/01/10 12:04 PM Share Posted 10/01/10 12:04 PM I had a similar sounding rattle that disappeared when I accelerated. it turned out to be loose exhaust mount, so check youre exhaust properly. I got someone to rev different ranges then that's when I noticed it. Link to comment Share on other sites More sharing options...

The flex plate could be the problem or I heard that the torque converter can vibrate and sometimes needs to be shifted around one hole. Link to comment Share on other sites More sharing options...
