WHY DOES MY TRUCK KEEP DYING?

1994 Chevrolet Silverado • 147,000 miles

Once the truck warms up, it runs fine until I stop at light and then it starts missing, cutting out and then dies.

Start by cleaning the IACV, EGR and PCV valves and test the TPS and MAP sensors-to include a fuel pressure check

Is this monitored static fuel pressure-possibly the IACV, EGR valve and TPS/MAP sensors

1.Defective spark plugs

2.Inadequate spark/coil,defective spark plug wire.

3.Lack of compression

4.False air leakage.

5.Faulty fuel injectors.

6.Insufficient fuel pressure.

7.Contaminated fuel.

8.EGR valve that is leaking.

9.Oxygen sensors.

10.Throttle position sensor.

11.Manifold absolute pressure sensor

12.Mass Airflow Sensor

13.Idle air control valve

Note: If it doesn't apply disregard it-
