'85 ur-q Cold problem
Okay I'm looking for suggestions here. My '85 ur-q has been running
fine up to this Monday when the weather suddenly became colder,
driving temperatures to and from work are now 5C or less.
With the cold weather the car has develped a significant hesitation
when pulling over 3K rpm, very noticeable in 5th gear but apparent in
the other gears. This is not the ur-q 4K rpm problem, feels more like
fuel starvation. Interestingly after a long drive about an hour the
problem seemed to go away. This leads me to believe that it's a part
that takes a long time to warm up? e.g. driving for 45 minutes it was
still not accelerating beyond 3-3.5k.
My first guess is the WOT (Wide Open Throttle) switch as the car
builds boost fine but seems to be struggling for fuel. I'm planning on
hooking up a DVM tonight to monitor the performance of the WOT switch.
Any other suggestions?
Thanks and regards, Mike
