Car starts OK but dies within about 10 seconds on a cold start. Hot start is no problem. Accelerator must be pulsed for about 30 seconds before engine will stabilize. Idle switch (motor) was replaced with only slight improvement. Cars purrs fine as soon as it stabilizes and no acceleration problems after warmup. I am thinking maybe PCV valve or upstream O2 sensor (Heck, I don't know if it has more than one.)

Check the fuel pressure. Attach a fuel pressure gauge on the schrader valve on the fuel rail, turn the key to run. The fuel pump should come on for 2 seconds and turn off. You should have 35-40psi and it should hold steady. How's your fuel filter. When's the last time that was changed.
