Re: '85 ur-q Cold Start Problem

 #      Second problem, under acceleration when the WOT switch operated the 
 #      duty cycle would drop to 50%. This indicates (on a MAC02 anyway) that 
 #      the idle switch is still closed. So I'd be happily accelerating away 
 #      until I hit the WOT switch, which instead of richening the mixture 
 #      actually leaned it out. Cool thing about this "feature" was the 
 #      temperature sensitivty of it. Hooking up a voltmeter to the idle 
 #      switch prior to this showed the idle switch to be functioning 
 #      normally?
... too bad we can't call up the OXS duty cycle on our trip computers, at 
least for those of us that have them (my 4k & 5ks do, the urq doesn't)

Thanks for posting your findings!  My urq has an occasional cold start 
problem (as if it really gets cold here) and I know that activating the 
idle and WOT switches makes the car idle much better ... I think I have 
a look see at the duty cycle!
