Probably should have waited for a reply first, but the idea sounded
like a good one, so I went ahead and did it. (Got the fire
extinguisher ready, just in case spraying a flammable chemical on a hot
engine did something... flammable.)
What an experience. A great sucking sound could be heard (I'd removed
the air intake hose), and the engine sounded like it was going to stall
each time I sprayed carburetor cleaner into the rectangular hole just
inside the throttle body. I sprayed a total of three times. Then I
shut down the engine, re-attached the air intake hose, and drove the
car around the block. So far so good. I'll have to wait about a month
to see if this did the trick...
