Throttle Sensor I am trying to find the throttle senser on a 1992 Geo Storm GSI. I think that it is causing the car to run at 2000 rpm when stopping at a red light. The idle will come down after about 1 minute.

Yes its that easy, just make sure you engage the notch on it to the throttle body shaft. You may have to roll it past the screw holes to engage the notch. Then holding it in place on the throttle body, just roll it back to where the holes line up for the screws. Do not over tighten the screws

most probably not, the GSi has a different head. Base has a 12 valve, GSi has a 16V. Check for part numbers. Do you need just the cap or the entire distributor?

great question. but confuses <STORM (an ISUZU) with METRO, Swift.
ill assume the STORM is correct and the 1.8l too.
that engine is a ISUZU Real engine,
and is called the
4XF1 ,see facts below.
now the cam answer.

in the uSA this car is the GSI model with 1.8L
see last link for your answer. below. GM official page.
you can also see your cam in the 2nd link below.
the engine is INTERFERENCE. so if the belt snaps, it bends valves
just like all HONDAs do.\

wiki facts.
The larger 1.8 L 4XF1 DOHC replaced the 4XE1 in North America and produces 140 hp (104 kW) and 125 ft/lb (169 Nm) of torque. This engine was used in the 1992-1993 Geo Storm GSi, in the 1992 Isuzu Stylus RS, and in the Asuna Sunfire. In Japan it was installed in the Isuzu Piazza, where it had 150 PS (110 kW).

rockauto shows the belt. see it?

Hope this helps.

same answer for all cars made 1920 to now.
never restarted ,ever ? gee , a little hint...?
1: lost engine compression hot, (gee forgot to do the 60k serviice/)
2: lost spark , yes, check spark at all 4 cyl. if bad check coil spark.
3: lost fuel or too much fuel called flooding.

one removes a spark plug, it drips of fuel , say all 4.
flooding.
crank motor at WOT, wide open throttle to clear flooding.
if the spark is good and the spark tips are dry, then try test fuel
if car starts and dies. then you lost injection.

easy huh> with the above you know exactly why it fails.
compression bad
spark
fueling.

1991 i think is TBI single injection engine, i can look it up but
no i wont. we need to do the tests first to get there.

Most engines don't fair well under extreme heat. It's apparent you might have some electrical issue's. Your rpm's or mph arm going up and down could be faulty speed sensor would cause arm problem. I think you may have more than one problem, the car shutting off is due to engine over-heating. Check cooling system-thermostat, water pump, radiator, engine fans and coolant temp sensor and fan relay's. It could be as simple as blown radiator hose.

The Geo Storm is was equipped with a 1.6L 4 cylinder engine,
the GSI Geo Storm had a 1.8L 4 cylinder engine.

I had these exact symptoms and found that there are two ground straps attached by ten millimeter bolts right near the throttle plate on top of the manifold. These ground the circuit you are describing.
Also the computer grounds a circuit which fires a relay that runs the fuel pump.
You have a blow fuse or are missing a ground for your circuit.

i had the same problem and i had to replace the fuel pump

try uplugging throttle sensor see if any change
