Hey guys,

Had a bit of an interesting issue start happening today. When i stopped at the lights my car began rocking/shaking slightly until i took off when the light went green. It felt like the rocking was originating from directly under the drivers seat. It was happening about 50% of the times i idled at the lights.

Any ideas whats going on?

low idle speed or a bad misfire

could be any of a number of issues
look at simple things first

air/ vacuum leaks
battery voltage
bad fuel
plugs
leaky injectors
dodgy sensors

was you tacho needle bouncing around at the same time?

Where were the lights - on solid ground or a bridge? It's easy to mistake bridge movement as a car fault...

Is the problem reproducible? If you rev it up a fraction while in neutral, does the rocking go away? Does it still do it when the air-con is off?

Was there someone sitting next to you giving you a handy-j??? I know when I am close to climaxing I get a bit jittery/convulsey.

LOL!!!!

Was the aircon on? I know my car has a rough idle when the aircon on, as did my mates facelift 3.0R-B.

Cheers for all the responses guys. It seems the issue has gone away so im not too concerned about it. I was on actually on a bridge at the time and the aircon was on so either could have been the cause.

i have had my gen 3 subi rough idle too, it could be caused by a leaking rocker cover. It says this in the gen 3 service manual under "engine trouble in general."
