I have a 92 Ford Bronco full size 5.0 litre 302 and it has rough idle and when warmed up to operating temperature stalls out. I have checked the IAC for proper volts and resistance and operation which all checks out ok, am going to check EGR valve tomorrow aside from that any ideas would be appreciated..

Welcome to AF. Check for a vacuum leak. Could be a hose off the intake or could be a rusted out vacuum canister. Also, check the PCV valve. If stuck open it would cause a major vacuum leak.
