jar of marbles sound like in engine
 
Hello guys. Just want to ask other MT owners here. Do you guys hear jar of marbles in the engine area during deceleration 1st-4th gear under 2200rpm? it's not continuous but after you put gas and let it decelerate(foot off pedal).

Jar of marbles noises from our car might as well be listed in the brochure as a feature. Well documented noise. Please search next time. :thumbsup:

It's not the engine I think, its shudder from "lugging"

I bet if you depress the clutch while it is making that sound it stops eh?

you mean when you put the car in neutral at about 40 and coast? clutch chatter is what you are hearing.

If you ever drive a car with a solid hub clutch you'll really hear the noise.

The likely cause is rapid loading and unloading of the clutch on the input shaft caused by power variations during the Otto cycle.

My advice, turn the radio on and don't pay attention to noises this car will drive you crazy

Not knock. It's like a loose chain inside. I run 91octane always = california.

Saw those posts but they really never answered it. did not read the whole explanation. I did have my engine rebuilt in front due to the idle dip, CEL plague. Not sure if it's related.
