ur-q cold running problems
There seem to be at least a couple of listers who are having problems
with their ur-qs as the weather turns colder. In an attempt to fix my
problems I swapped the control pressure regulator (aka the warm up
regulator). The good news is this seems to have fixed my cold starting
problem. With the old CPR the car would refuse to start after sitting
outside in cold weather and require WOT and 2-3 minutes of cranking
and feathering the throttle before I could get her to idle normally.
This seems (need a really cold day to prove it) to have been fixed by
swapping the CPR.
The second cold weather problem is a hesitation, feels like fuel
starvation above 3k rpm, this is most apparent in 5th gear but
noticeable to a lesser extent in all gears. The new CPR has not fixed
this problem. I'll be taking a look at the following this weekend and
would appreciate more suggestions:-
1) Temp sender and connector, below #1 plug
2) Distributor cap
3) Replace/check vacuum lines.
I've already done the auxilliary air regulator, plug wires, and plugs.
Thanks and regards, Mike
