SOURCE: cant find temp sensor on 1992 saturn sl2
On the SL2 (DOHC), there are two coolant temperature sensors located on the left-hand side of the cylinder head, near the upper coolant hose. On the SL2, the upper sensor with ONE WIRE controls the temperature gauge in the dash. The lower sensor with TWO wires provides input to the computer. They are not interchangeable. Here is a tip you will need a 14mm deep socket or box wrench. The new sensor may require a 13mm socket or wrench, depending on the manufacturer. Good luck and hope this helps. Keep me posted.
SOURCE: Where is the fuel filter on a 1997 Saturn SL2?
It is an inline fuel filter under the car in the frame rail up front neat the motor area. It will look similar to this...
On that saturn it has a hose already attached to the fuel filter. It has what they call quick connects on both sides. just remove one side of air intake. (the one closest to firewall of car) where you can get your arm in there. Reach right under fuel filter and grab two white or green tabs with pointer finger and thumb. and squeeze till they make a snaping noice. then all you have to do is reach under fuel filter and pull hose off. Then push the black clips around fuel filter out and it should slide out. The same on the hose already connected to the fuel filter

Inside the coolant reserve tank there is a sensor for coolant level.
Over time,this sensor can get stick.
Inspect the coolant reserve tank for crack or leak.
Locate the coolant level switch/sensor and soak it in clean warm water.
Make sure it's free to move up and down the float path.
Top off the coolant tank with coolant only.

my only guess is a vacuum hose leak. possibly a loose air filter housing, or the mass air flow sensor. look for any hoses unplugged. if nothing is noticed, try cleaning out your fuel system. if that doesnt solve it, then it would be something an experienced mechanic would have to come and examine it personally.
