I have a 5 speed 1999 Mazda Protege. When the weather gets hot (above about 90) and I drive the car for more than about 30 minutes, the engine light comes on and the car starts to ‘hesitate’ and eventually stall. The temperature gauge never goes above normal. To restart the car, sometimes it is enough to jump start the battery. After cooling down, the check engine light goes off and the car is fine. Twice I have taken the car in to a mechanic, where I was told there was nothing wrong.
Anyone have any ideas?
