i have noticed that a lot of EF/EL have a vibration at idle it goes away if you idle up by a few hundred rpm. it seems to be in most of the higher klm cars 190-240,000 any ideas? it seems to be at its worst when in drive.

Suggest autos are starting to get a bit old....maybe changing/flushing the tranny fluid will fix your trouble?
Or you could check the engine mounts.

possibly a worn or collapsed engine mount - just replaced the RHS one on my mums car cause it was stuffed, commo V6 have this prob a lot.

I know my headgasget has a slight leak into one of the pistons and it does exactly this...

Have come across this and found that it was due to a faulty Hego sensor not tuning the engine properly. Hope this helps.

I had the same prob with mt 95 EF 4.0l 5spd 160,000k, causes were:
1, carbon build up in the throttle body
2, dirty injectors
3, dirty fuel filter
4, dud coil pack

After having these fixed it idles much better. Goes better too :)

I have noticed my EL has the "shakes". Not the smoothest idle, but engine runs good after a few 100rpms are applied. Havn't got round to finding the reason as it hasnt really bothered me so I'm in no rush. Could be dirty injectors or fuel filter, could also be the plugs (yes I'm too lazy to check them) or the leads. Mine has done 176k.

What is a Hego sensor?

O2 sensor - measures how rich the exhaust is.
