This is a obd 1 system, you need a scan tool that is obd1 compatable, but having the blink code is just as good. The diagnosis for this is fairly complex and can't really be conveyed in a text. In general however, if you have other active codes (53 or 62) fix them first. It also may have been self induced. If it is the only code clear it and confirm that it comes back on is own. Also, check for a poor ecm ground...not sure where it is on this car...very commonly found at the thermostat housing stud.

look for tube coming up from left or right of motor if its missing,

I had a similar problem with a 2000 Sunfire. The temp guage was not reading and the t/c light was on. There were no codes displayed. After some research I checked the resistance of the coolant temperature sensor and it was much to high. 100,000 ohms and should have been 2000-3000 ohms when cold. A new sensor solved the problem. There are other things which could cause your problem but this solution worked for me. Replacing the sensor is easy depending on it's location in your car. You might have to drain some coolant. Be careful and take precautions. Do it when the engine is cold.

-No fuel enter to the cylinder, bad crank and or cam sensor. Good luck Mai

Probably, it is the fuel-injection pump that cannot supply the necessary gasoline as quickly as needed. So, it "starves" and stalls. Try removing the gas-tank filling-plug, to let some air into the gas-tank -- there could be a "vacuum" that prevents the pump (which is inside the tank) from pushing fuel.

is it efi engine or carburator ......you may nedd to clean intake throttle body......

could be bad power wiring to fault injector or injector itself it could be clug and have the fuel filter change

The coil pack rests on the back of the engine, under the intake manifold. Make sure the engine is cool. Follow the plug wires to their ends and you'll see the coil pack. Mark the wires with tape and number them 1-4 so you know the order the plug wires are in. You'll need to remove the entire ignition pack to replace the coils. Three 10 mm bolts hold it in place. Remove the marked plug wires from the pack, unplug the two wire connectors. I worked the pack out from underneath the care. There is a crank sensor on the back of the unit - be careful not to break it as you remove the unit. Take the pack to a table and remove the 4 small nuts that hold the coils in place. Clean all the connectors and apply some dielectric grease to all the electrical connectors. Add some grease to the o ring on the crank sensor and clean all the other parts. The 4 bolts that hold the coils on can only be replaced by pulling the entire unit. Install the new coil spade connectors into the base, being careful to align them properly. Snug down the 4 small nuts that hold the coils on while holding the bolts that secure them with your fingers until the get tight - be careful that the bolds fit into the recesses that hold them squarely. Replace the unit in the car as you removed it with the three 10 mm bolts. Be sure to follow the numbers on your plug wires as you replace them. Reconnect the two wire connectors after cleaning the contacts. Replace the ground to the upper right bolt of the pack. Now would be a good time to replace the plugs and plug wires as well! Took me about 2.5 hours.

Visit your local parts store, ask to see your water pump replacement...your water pump is an internal model that switches out without to much labor. Unbolt the water pump pulley...the water pump is held in place with 5-6 small bolts...bwe sure to properly seal new gasket ...(Lock-tite blue or red)

I think it is a O2 sensor of a ELD sensor but probably an O2 sensor

The fuel filter is located under the car towards the back directly behind the fuel tank, fuel tank is positioned forward of the rear wheels nearly at center of the car, the FUEL FILTER has 2 threaded metal fuel lines attatched to it.

This part may be found best at a salvage yard, is your question about the part or how to replace it?

The TCC solenoid in the transmission needs to be replaced. It is under the side cover. It controls the converter to lock up for better fuel mileage. If you want to drive car until you get it fixed you can un-plug the connector going to the transmission on the front of transmission. This will keep it from going to lock up mode and keep it from stalling until you can fix it. Common problem.
