Wondering if anyone has experienced this problem or can point me in the right direction.

When my truck comes up to operating temperature, it tries to stall. If I catch it, I can blip the gas and it stays running. Never does it again. Only does it as the temperature gauge comes up to operating temp, and only if idling at stop.

Any help or suggestions is greatly appreciated. Thanks
