Even so this sounds so simple, change the thermostat. Couple of years back I had the same issue and couldn`t figure out why it ran warm on the interstate but not in stop and go traffic. I finally thought "I wonder if the thermostat is staying open" I removed it, put it in a pot of boiling water with a temp gauge and found it stayed open after it got up to opening temp, when the water in the pot finally cooled below a 100 degrees, it would close.
Since then I have found it`s hard to get a good thermostat, regardless of the name brand, every name brand I tried has failed on me so I kept buying stants until I got a good one.
