Engine begind to fail and later stop.
Here is my case:
RAM 1500 , 1994, 4x2, 5.2 L
In idle, when is warm or hot, it begins like a hissing and later, engine stop.
I replaced the IAC valve.Same thing. Replaced wires for sparks and distributor. Checked Throtttle Position Sensor. Looks OK.Checked Engine Coolant temperature sensor. Looks fine. Checked MAP sensor : Wrong values. Voltage is good in lows RPM, butdoesn´t increase as increases of RPM.
error codes: #21 O2 sensor
#73 Transmision temp sensor
