My Duc has developed a miss at idle when it's cold.
Even with the FCR's it would alway start first go, no throttle & just lump over (i love that sound) as it warmed up.
Now it has a noticable miss when it's idling cold, which is just enough to shut the engine down. I find i have to hold a few revs on it now to get it over the miss. Once it's warm, no miss, no problem!
It stalled twice on me today taking off cold when it missed.
I've ordered a set of Dyna Coils from Chis today, had always planned to get them anyway.
Would it be the std coils breaking down?
Maybe the HT Leads?
Plugs are new Iridium DPREIX-9
Any idea where to start?
