While running it will start cutting out and loose power up hills to a standstill. when you push on the gas peddle it will start sputtering and you will have to let out on the peddle a little for it to stop and maybe start some momentum.. the motor stays running cutting out and almost like chocking but never dying..
Have the fuel rail pressure checked and change that fuel filter!

Check engine light is frequently a loose fuel cap, but the other problem could be a bad fuel pump, or a clogged fuel filter. Try the fuel filter first - its the cheapest.

Just a little suggestion. IF this is a 1993 it is fuel injected.the car starts and runs for a few seconds and then dies. You are on the right track by checking the spark and fuel delivery. If you have both of these when it dies i would check injector pulse. the use of a noid light would be the quickes method.They can be purched at the parts house for pretty cheep.If you have no injector pulse then it cuts the fuel off to the engine.Replace the ignition module (contols spark and injector pulse) i have ran across a few that will lose only one of the outputs, insted of both of them. Now if you have fuel and fire, i would check to see if the cat. converter is damaged or cloged thus restricting the exhaust and stalling the engine. Hope this helpes.
SOURCE: Dies when idling, does better with a/c on, but still dies
this is your problem:
Here are the most common causes of surges, stalls at stops, low erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Check your EGR valve, IAC valve, fuel pressure regulator, fuel pump, fuel filter, spark plugs and spark plug wires
