I got a 2004 alero with the 3.4l back in February this year and since I got it it had had a shaky idle, it is not smooth and I can feel it go up and down. It isn't that bad, but i like my cars to be smooth it has been annoying me.
I took it to the dealer months ago, they hooked thier computer to it, and couldn't find anything. Their diagnosis was that it was normal for this engine, I am still skeptical. Does anyone else have this issue, or can tell me what to check?
