If it runs ok warm, check the temp sensor in the coolant TEE at the front of the engine. Should be 2,000 to 3,000 ohms at room temp around 70 degrees, then 250 to 400 ohms with a warm engine. Also check the wire and connector at the sensor because a bad connection will also cause problems, but make it run real rich when it warms up.
