Split second stumble at idle sometimes?

Alan l. · 09-08-2009, 10:02 AM

My new Msport only has about 600miles on it and its a 6MT that is bone stock power wise.

Occasionally while i'm warming up the car or if i'm idling I'll feel a split second shake from the the car. Happens maybe once every 20-30 seconds....sometimes longer intervals or it doesn't happen at all. Not a huge concern but just wanted to know what causes this and if I need to pay a visit to the dealer.

Mine does this too sometimes, even more frequently. I'm assuming its the same thing...a brief shudder you can barely feel but know it's there?

Yeah you could barely feel it but if you are just sitting there while the car is idling and the radio off you can feel it. Its super brief....by the time you feel it and look down at the tach its gone.

This has been an issue that has been discussed a ton. Not sure of any findings but try to

and see what you find. Seems this happens to pretty much everyone to some degree, everyone has their opinions, but I don't think there has ever been a definitive answer.

yeah i tried searching stumble but its one of those weird things that could be described a number of ways so I was getting a bunch of random issues.

I guess its good to know that its a common thing on the n54 and not something wrong with my car.
