Rough running / high EGT

Thank you Jeff.  I will start with checking #2 spark plug and connectors. 

Hi all

Just to clear things up a bit.  In the software of the ECU the 912iS indeed reads the EGT.  In this case it is a reporting only function and any change inside the cylinder would be reported in the data stream to the BUDS log files.  

In the case of the type 915/916 this has changed, the EGT actually will is used by the ECU to make changes in fuel flow (pulse duration) and timing as in the case of knock.  

I think Jeff is right, try moving the EGT to another cylinder to see if you have a problem with that cylinder or the probe itself.  EGT probes do fail even at low hours.

Cheers

Thank you. I will be traveling for the next 10 days and will not be able to provide results of troubleshooting until after travels. Thanks for suggestions. I will keep you posted. Drew
