Stalling Issue
I have another thread out for this problem but cannot find it for some reason. I have a 1991 Ford F-250 5.0L. The truck starts up fine but stalls during idle when engine is cold and temperature is below 45 degrees outside. Idles great is when engine is warm or weather is above 50 degrees. I retrieved codes 32 and 33. All the codes pointed towards the EGR. I replaced the EGR valve, electric solenoid and position sensor. I have also changed the coolant sensor and the A/C valve. I do not have the codes anymore but I still have the stalling issue. Any idea?

The Idle Air Control(IAC) is well known to cause idle quality issues. Perhaps you should try cleaning it?
