check your thermostat, may be stuck part way open, idle would be okay, hiway driving would provide enough cooling when moving.?
sorry, only thing I can think of.

Thanks for your reply, but I sold it in March. It had too many problems other then the cooling system. I now drive a 1994 Honda Civic and it is a great reliable car!
