sounds like your sensor is bad. Check it with an ohms meter. put a lighter on it, if the reading goes down as it gets hot, and back up as it cools. it should be good. otherwise replace it.

The IAT (Intake Air Temperature) 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 intage manifold. Engine with exhaust brakes are particularly prone to IAT sensor fouling because soot is blown back into the intake during valve overlap.
I have a 1998 Metro with the 1.3l and the Camshaft Position Sensor is located on the bottom of the oil pan.
Remove the negative battery cable for 30 seconds. This works on pre '96 cars.
It's either in the intake or in a hose between the intake and valve cover.
that must be some metro to have a big block
under he motor mount
The trouble codes 23, 31, and 32 for a 1993 Geo Metro correspond to the following issues: Code 23: Intake air temperature sensor circuit high voltage Code 31: EGR system malfunction Code 32: Exhaust gas recirculation circuit malfunction
you have to remove the head first.....
it is located on the head
It is possible as the signal from the oxygen sensor is sent to the computer
connected to the air cleaner housing
