Cleaning the IAT sensor
#12
the "old" starting fluid should be ok... the newer stuff leaves a residue... like you said ether... but good luck finding it, most places just sell "starting fluid" which is a whole different breed

The IAT sensor measures the temperature of the intake manifold. The ECM uses this sensor reading to set injection timing and adjust the air-fuel ratio. If the fuel mileage and power output of you engine seem low, some owners have found improvement in EGT, fuel economy, and power after cleaning carbon from the IAT sensor in at the rear of the intake manifold.
