my SES light recently came on, i assumed it was gonna be a p1320 how ever when i got the light checked at autozone it was p1321...their description said it was knock sensor #3, is the knock sensor the same as the ignition coil? Since the light came on i've had intermittent rough idle and also the car has stalled on three different occasions while i was in park, i'm just lookin for some input or direction on whether my issues are strictly ignition coil related or if there is something else

 

bump......
