Thanks for the response, Rod. I rushed home after work last night, and stod
over the engine, carb cleaner in hand. Then I realized I had no idea what kind
of results I should be looking for! Will the carb cleaner make the revs drop
when the leak is found, or will I see bubbles? Flames, perhaps? I'm making
the assumption that the engine should be running when doing this exercise...
Also, I came across an interesting phenominon when driving in this morning.
It was warm this morning, so I never bothered to turn on the climate control.
Revs were consistent at 1,400 RPM's. Sitting in traffic, I started playing
around with the climate control. As soon as I pushed the "auto" button on the
climate control, the engin jumped up to 2,000 RPM's. Push the off button,
engine SLOWLY sank back to 1,400 RPM's. This is interesting, I thought. The
climate control has been malfunctioning since 1989, but has never interfered
with engin performance before, before it was just a guess as to what
temperature air was going to come out of the vents (50/50 chance cold or warm,
no matter what you had the display set at.) Wassup with that??? Anyone ever
had a screwy climate control that futzed with the idle speed before??? This
thing really has me baffled! TIA for any suggestions.
