I wonder if there's a link between some of them running rough and the clutch wear? When the car is choking and stalling, one tends to try and catch it with the clutch and will likely give a bit more gas and ride the clutch on pulling away to avoid stalling?

If this were the case, then would the clutch wear be attributable to the driver? Or a consequence of an engine management problem?

I'm no expert but wondered if there was any pattern here with those that have had clutch problems?
