Ten minutes into the 20 minute drive home from work the engine quit
missing and seems to run fine now. Runs smooth and has full power.
Not sure what to make of it. I suspect this will not be the last of
this problem. Thanks to everyone who responded with ideas and info.

Has anybody had any ignition coil or igniter problems?
Last night I was mounting my aircleaner and knocked off one of the
spark plug wires without noticing it until I started the engine.
It
ran very rough and I could hear the snapping arc jumping from the
coil to the wire..... about 1/2 to 3/4 inch. It probably ran for
less than a minute, just long enough to get out see the problem and
then go shut the engine off. After putting the wire back on I
started
the engine and it ran smoother although maybe not as smooth as it
used to. It was late and I didn't think too much of it at the time
thinking the plug may be fouled and would clear up.
This morning it was harder to start and ran rough on the way to
work. When I feel the temp of the exhaust pipes the one cylinder
pipe is noticeably cooler than the other three. I pulled the
fouled
plug and bead blasted it clean. No improvement. Still runs rough
and that exhaust head pipe is only warm not hot like the rest. My
check engine light so far only blinks a steady flash, no code.
I'm
starting to think I may have toasted a coil or igniter when the
spark
plug wire was disconnected. Or one of the two was already weak
because I've been having a bit of a starting problem that I had not
worked out yet. Tonight I will do the "ignition control system"
checks listed in the Fuel Injection System info that was posted by
Darrel Boehler a few weeks ago, thanks Darrel. If anyone has any
info I'd be glad to hear it before I dive in to this one.
