I have the exact same problem and have had it since I purchased the car last month. Temp is fine on the freeway but climbs up to almost overheat on side streets or in traffic (although it never does go up further and actually overheat). My mechanic told me I need to have the rads cleaned as they have not been removed and cleaned in the 95k/18 years. I decided to replace the radiater with a new high capacity performance one as I was told it will make the car run approx. 20 degrees cooler. I figure the extra $500 is worth it if it will help to prolong the life of the engine. I am taking it in next week to have it done... I'll report back with the results.
