Could someone give me an advice, please ?
In Legacy 92
I feel engine vibration at idle when rotatons drop to 350-400 per min.What can be wrong with the engine?

Thank you for your help.

Can be mounts.
Check engine, tranny, and rear diff mounts.
If you haven't changed them, those are 10 years old rubber, you know..

1) It shouldn't be idling that low

2) DO NOT clean your IAC valve unless you know exactly what you're doing. I went and tried to clean it and really screwed it up. I had to go get a new one from the dealer b/c there is no aftermarket and here in FL there aren't BC-BF Legacies laying all over junkyards. Needless to say it wasn't cheap.

P.S. If you must clean it, use brake cleaner instead of TB cleaner
