For the record, I went stumble free after a service soon after my last post in this thread.

Then about 60 days ago, I had some work done (new flash, new plugs, oil change, etc.) and they brought the car down the ramp for me, and it was misfiring something fierce.

They sent me home in a loaner, and hte next day they said they hadn't reset something after then new plugs were installed ( ). Well, sure enough, the car has the stumbling idle again.

That, combined with people talking about ignition (plugs and coilpacks), I'm wondering if this isn't a fuelling or valving issue at all, but an ignition one? Is this a bad connection/misfire type of issue?

Anyone else had any success getting rid of the stumble?
