Re: Cold help



Idlespeed motor has absolutely no effect when throttle butterflies are 
at anything other than closed (that's what the microswitch does). 
Sounds unrelated, and most likely the control pressure regulator. So 
far I've seen 3 cars with this problem. NB it's NOT the same as on the 
Volvo, you have to get it rebuilt or a new one. That particular CPR 
was not used on any UK cars. It's also called teh Warm up regulator. 
It sets the resistance to movement of the metering flap during warm-up 
and if it puts too much resistance, you'll run lean and cough and 
splutter.

I had a CPR go bad (was actually Rich's in my car) and it really did 
go from running fine to running badly to not running at all in the 
space of about a week. 

Ken Mills in London can rebuild them for £100ish
