Thanks, Bernd. I'll the check the coolant temp sensor. As for the O2
sensors, they have never been changed. After all that has mentioned
about them in the past I didn't even think about them. Would that have
anything to do with the rough idle? It's not aggressive cam rough it
feels more like it's missing but there is no sign of that when you push
on the gas.

Subject: Re: DML: Hesitation when cold
(1) This is normal (to an extent) as the system is going from a
Cold-Start/Open
Loop operation into normal/closed-loop. There will be a slight "hiccup"
on
higher mileage vehicles during this time...especially on 5-speed
vehicles.
(2) Change the coolant temp sensor as they do corrode after a while and
will
give slower warm-up readings (or sometimes too warm at cold-start
causing
a "hiccup")
(3) How old are your O2 sensors?
