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.

There could be many issues. These codes read your engine is running too lean. Check : all your vacuum hoses for leaks, PCV valve and hose, MAF sensor. This may require an experienced technician to figure this out. Hopefully I help'd!!

Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, 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.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, 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.

Testimonial: "Thank you, I'm sure if your advice it was I'm looking for. But at least if this works, it will save me a lot money from having to replace expensive sensors."
Find your air mass flow sensor in the stiff collar of the air ducting immediately after the air filter. Have the engine running and disconnect the plug to the MAF. If this makes the car run evenly again you need to replace the broken MAF. The misfire on plug 4 I think is a downstream event of the MAF not sending the right info to the ECU and consequently not providing the right fuel / air mix to the engine
