    car is a 03 gtp. merged on the highway at WOT then rpms started to flutter then she broke down on the highway.

    temp light came on, SES light came on, scanning it here soon car did not overheat, nothing broke that i could tell at WOT such as a lower end prob

    no fluids leaking, checked all connections, vacuum lines, no moisture in the engine bay.

    just replaced the t stat and changed coolant to eliminate a stuck t stat and it started for 10 mins now its dead again and wont start for more then a sec.

    i could have sworn i just blew a vaccum line off at full throttle since we have all been there before and it felt like that but i cant explain any further.

    im thinking its just a bad sensor? any ideas?


    ALSO: i have not many any changes to the car recently
