Hello,

With the throttle closed:

On a cold start, after sitting at 15 degrees C or less for a long while the
Vanagon starts fine.  On a hot start, the Vanagon starts fine.  However, if
left for a long time at about 20 degrees C, or if allowed to cool so that
the engine temperature is about 20 degrees C, the engine fires weakly, but
not quite enough to start.  Persistent cranking results in the smell of
gas.

However, if the throttle is opened in the 20 degree C condition, the
Vanagon starts right up and idles fine.

I have had the car since new, and have always noticed that on any closed
throttle cold start, the engine idles slowly and will idle a bit faster
after one blip of the throttle.

I have checked the coolant temperature sensor and the air temperature
sensor at the computer wiring harness, and both are in spec at 20 degrees
C.  The throttle switch looks fine at that connection as well.

Any suggestions?

Thanks,
