Well, part of the problem was solved - a bad spark plug wire on #1 cylinder. However, it is still missing and idling roughly, just not as bad. Tech will spend more time on Tuesday.
If it turns out that the next step is the throttle body/AM sensor, is it very hard to remove? Is there anyone who,if it is easy, would be willing for me to try their's for a few minutes to see if that really is the problem, before I spend the big $$?
On the same note, any great diagnosticians out there? I am in the SF North Bay, Marin County.
