My 94 accord swapped a H23a engine in, after i swap it, the engine light is on, it's said the problem is come from the oxygen sensor, i try all the thing to fix it, i still on. So I do care of it at that moment, at least the car can run. But one times, when I am driving on the highway, the car suddenly lost all the power, the car won't go, and then the engine stop. I can't get it start again. Do you guy have any idea will cause like that?
