Re: '85 ur-q Cold Start Problem

 #      Second problem, under acceleration when the WOT switch operated the

 #      the idle switch is still closed. So I'd be happily accelerating away

... 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!
