Hi Wolf,
it is a Newbie like me, so always the same questions. It needs some time to read all stickys or results after searches. I did many silly questions too, and there are more to come. For example, I'm busy with all the stuff around ignition, truck stumbles a bit. And there are tons of material to read about that here, but despite that I ask the folks.
And I asked you, and I'm always happy with the answers, much of them help more than the reading.
