I have dual Lightspeed Plasma III on my IO 320 B1A with Airflow Performance FM-100 injection. I run the Denso IK27 as suggested by Klaus and replaced my plug leads last year , again, as suggested in the maintenance manual. My Fuel injection was inspected and serviced by AFP this year as suggested in their manual as well. Recently, I've noticed a roughness or a missing at idle. My EGTs and CHTs are grouped nicely in cruise running LOP with the only outlier being cylinder #1 which runs about 30 degreed cooler than the rest. I get the sense there is something not right in my ignition but can't put my finger on it. I asked Klaus how to tell if individual components in the ignition system are functioning properly but don't get an answer. Could there be a problem in one of the coils? Modules? are the new leads the problem. The troubleshooting flowchart notwithstanding,I'm reaching beyond my knowledge base and experience. It used to fire right up and run as smooth as can be but now it takes a little more effort to start and round a little rougher at idle. Any guidance would be appreciated.
Cheers,
David
