I would suggest replacing it.
Bad TPS, plugged exhaust,bad CO2 sensor many things you need to get it tested by a mechanic
The fan switch is a sensor located in right side of the head
under dash drivers side on the 4 cyl engine
1-2-3-4-5-6 is the firing order
Coolant weeping and noise.
Defective Coil pack, defective spark wires, plugs. Bad ground(s). Open (electrical short) in starting system. Faulty Ignition switch, ECM, other.
may be a bad TPS (throttle position sensor) if Fuel Injected a 92 so I would assume so.
I have a 1989 sunbird with the 2.0 and under air cleaner on one of the intake runners is casted on there the firing order, not sure if there all like that, but you can start off looking there, if you don't have a Haynes manual.
