Re: [DML] Delorean Stalling Out (DMC Joe)

I totally agree -- problem could well be the idle speed motor.

My Z7V (B27E) came with CIS grafted onto it in lieu of 
an aux air valve. Was hard wired always active because the fuel/air
mixture unit had no place to attach a microswitch (totally different
throttle plate casting). Throttle plate bracket didn't have a screw to
trip one anyway. Worked OKish for a while, but became very twitchy
within a couple of months. One day the idle speed motor stuck closed
at a stop light. Of course totally killed the engine. Had to crack the
throttle plates open with the accelerator pedal at every stop to limp
home.

That's when I figured out what the "forbidden" brass screws are for
(which on European spec PRV's of that vintage are MEANT to be used).

I too recommend troubleshooting CIS first (if worse comes to worse you
can drive the car off the manual idle circuit or simply crack the
throttle plates open with the lower set screw until it is again
operational).
