Re: UrQ Cold Driving Problem
"Sounds right (been a little while since I looked). It's right next
the A/C solenoid valve (I seem to recall a mass of hosery all coming
together in big knot!), I believe. The A/C solenoid is a short squat
thingiemajig, while the aux air vavle is tall and slender. There is
a small hex bolt at the base of the tall slender tower -- loosen that
bolt and you can slide the assembly back-and-forth 1/8 to 3/16 of an

if you try both extremes, the "lukewarm idle" will be noticeably

little screw at the other end of its travel from where it was when I
started, the car could just about survive the rough period of idle. It
stalled once but when restarted it managed to stumble through it.
Interesting note, during this time, no amount of radical adjustment to
the static idle speed screw made any difference to the idle at all. Any
more thoughts. Thanks.
