OK. The RV-6 has been running like a champ. Last week my partner and I performed the GAMI Lean Test to see if any of our injectors needed to be re-sized. John Paul from GAMI called back after he analyzed our data and said, "Don't touch a thing. You are exactly where you want to be." Great news or at least it was until yesterday.
Flew the airplane yesterday from Charlotte to Cincy to see a friend. We generally run the airplane LOP now with tremendous success and efficiency, so I settled into my normal leaning procedures during the climb and cruise. At cruise I noticed the number 3 EGT was higher than normal. Normally all EGT's are very close to each other. Not today. See pic Below:

Then I switched the engine monitor to Peak Mode and noticed I could not get the airplane to run anywhere near LOP as it normally does and observed these numbers. I can normally lean to about 50 LOP and 7.2-7.5 at altitudes above 10,000' See below:

Anyone have idea what's going on here? Clogged injector or fouled plug maybe? I performed a "mag check" on the dual EI system on the ground and in flight and all seemed normal.
