The clutch sensor affects this one, gives signal and usually makes the advance and flow decreases so that you can get out of RPM and you can get better, if it comes out in the scann, the connector is to be checked in case it is evil or it is broken ... put that it has been given a sign of "clutch stepped on There the smoke ..), is what seems to me the relate that the clutch sensor can have in this. You will tell us what I am. Greetings Antonio1 !!
