Answer
Claudiu,
 Try changing the temperature sensors in the top of the thermostat housing, these go bad, and could be your problem.  Also make sure the engine has had all spark plugs, wires, distributor cap and rotor replaced in the last few years.  This will help quite a bit.

 Hope this helps,
 Josh
