You have a vacume leak, and once the temp sensor starts to read after the warm up the ecm starts to control. I would also check IAC idle air control valve.
if this is a 318 they had a problem with blowing out the valley pan under the intake causing a large vacuum leak. it will also us oil because of this. you can run a vacuum test on it or remove the intake and replace the gasket
Try unplugging the mass air flow sensor and see if it levels out.If so I would change the mass air flow sensor.If not try the same technique with the throttle position sensor.
When you first start driving it usually takes atleast 4 miles to warm the transmission to operating temperature. The temp of the motor may say it is warmed up, But, the trans fluid and differential fluid only begins to warm as you drive and the parts are actually working. THe computer has sensors that keep the trans from shifting to OD until the temp is up as not to add stress to the motor until warmed properly. Hope this helps and have a good day.
