97 Explorer 4.0 OHV
Have a 97 4.0 ohv that runs and starts great when the temp is above 75 outside. Below 75 it starts easy to alittle hard to start, soon as the engine starts to get up to temp it dies. if it restarts. If I keep the engine reved it will stay running when it gets to temp but if I let off it dies.
 






Could be bad iac valve or vacuum leak
 






Changed the IAC Valve.
