it ran fine yesterday, I changed oil last night using mobil 1 10w30, a fram high mileage filter and lucas oil stabilizer I put a little over 5.5 quarts including oil stabilizer. Started it after oil change and drove to store it was fine then, but today is when problems started.

had a mechanic spend four hours going through it and replaced fuel filter and spark plugs no positive results car acts the same. The mechanic was completely stumped as to what is wrong getting no codes and everything seemed fine by scanner and checking all vacuum lines and all connections.
(scanner says car is okay to drive) mechanic thinks either computer is bad or timing is off slightly (doubts timing because car runs to smooth at idle, startup and killing seems normal).

today car overheated, I think the thermostat froze shut is it possible that my whole problem can be vapor lock or a cooling problem? Will replace thermostat and coolant temp sensor tomorrow.
have the same problem?
