Wonder if someone might confirm for me whether or
not the device - quite large - sticking into the
intake manifold nearest the air intake is the intake
air temperature sensor on an 85 Olds 3.8 ?
Confusing me is the fact that there are 4 terminals on
the connector, and Haynes says it's just a thermistor...
If it helps any, unplugging it doesn't set a code; but
does make the engine run at a very high idle... perhaps
2000 rpm or so. Plugging it back in makes the engine
slowly go down to normal idle speed.
And if it matters, the tampering I'm doing is looking for
a reason for incredibly bad mileage. Lucky to get 10 or 12
miles per canadian gallon.
Thanks in advance, and take care.
