I thought this was a byproduct of that spring in the cluch slave cylinder. And thats why people were taking out the spring.04 elantra cvvt said:Put the car in first gear, and run it up to about 4 grand, the push in the clutch and let off of the gas. Just notice how increadibly long it takes to return back to idle. Sometimes, I just put it in second and let the clutch out for a second to make the R's drop.
