Hi,

My AUIII XR6 has been rough with a miss for a while. So I have replaced the plugs, leads and coil. Didn't change a thing, still rough, so I decided to get a non intrusive spark tester onto it while it was idling. Sure enough cylinders 3 & 4 are missing...... Well I'm a bit stumped. Good coil, good leads, good plugs. Just to humour the situation I thought I would swap the plugs around in case one had a cracked insulator but they were fine. So it was suggested that it could be the crank angle sensor. It's not a consistent miss but it's not far off. How likely is this? Any other ideas of what it might be?

All the injectors feel (by touch) like they are firing but I would not be able to pick up a quick miss.

Cheers
