Help with Stalling Issue

Just for a new addendum on this string; had the same issue with my 2009 DN-01 - it all came down to fowled plugs as well. Put new ones in and it fired right up and stayed steady at idle; used copper Autolite 4303's instead of iridium NGK's, because that's all I could find at my local auto store that cross referenced with NGK SIMR8A9 - they were also $3 vs $17 per plug. I will switch them after the iridium's come in on order, but for now she is running like a top.
