Have a Nice Day? Help: MY00 shakes at idle; even after warm up?

Like stated it's a MY00. I just hit 8000 miles. At idle at any time the car shakes somewhat. Sometimes worse than others. It almost feels like a hesitation. It feels fine when driving. At 6000 miles, I changed the oil and replaced the spark plugs. I used the reccommended NGK's. I've since checked and rechecked the plug gaps and seals. Oil was Castrol syntec blend 10w30 and the filter was Mobil-1. I reset the ECU and the car idles at about 1100 rpm cold and about 500rpm warm. It doesn't feel like it's going to stall or anything, but is quite annoying and I'm kind of worried. Should I make an appointment with the dealer or this something I can fix myself (hopefully!) Please help! Thanks!

Those numbers are normal. Your vibration could be a loose plug wire. I had to crank down on the plugs, more than I would like to, when I changed them, otherwise the wire would wiggle out. Check to make sure the plugs are in straight. The engine vibrates a little anyway.

But one of the things that was touted to me about the boxer engine is that because it is horizontally opposed, engine vibrations are significantly less than a V-4.

Do yourself a favor, have a friend quickly and slowly rev the engine (different responses, loads etc etc) while the hood is open and see what it is physically doing. Check your engine mounts, listen for anything unusual, watch how it moves. See if you can see something physically wrong like that. You've got 8k miles on it. How hard were they?

A moderate 8k miles. No racing or auto-x. City driving and a few short trips. Although, I do tend to be racy sometimes.

Hmm....mine does the same thing. Almost feels like a miss when its idle. Its not constant though. Once you rev it a bit, its purty smooth. You can usually feel it at the stop light.

How ruf is the "bump"?

I've had this exact problem, actually still have it slightly. Double check your plug connections, mine came loose on #4 and fryed the ignition coil. Not fun riding to the dealers on 3 cylnders, sounds like a 2 stroke lawn mower. I've got to tighten things up this weekend and see if it helps.

huh. My car just started doing this yesterday. I checked all the wires and they are fine.

The engine is as smooth as can be Everywhere except for idle. As soon as I hit the gas, it smooths out. Even if I hold it at 1,000rpm's with .5% Throttle angle (According to S-AFC) it is smooth.

I opened up the hood and the engine seems to be shaking about as much as it should. It's hard to tell.

If I pull a wire while it is idling, I get a really bad Misfire (Obviously). If I listen to the exhaust tone, It doesn't sound like a miss.

And Finally, When I floor it and Hit the Nitrous, It goes fine without exploding like a miss will do in a nitrous engine.

So, I have no idea what it is!

Huh, maybe it's a quirk we'll just have to deal with. I'll let you know if there are any changes or fixes!
