Upon accelerating onto the highway, after reaching highway speed, vehicle stalls and would not start. Flooding engine, gasoline coming out of exhaust, engine would not restart. After research and replacing leaking lower intake manifold, this was not my problem there was no leak. After more research I replaced more sensors and eventually cylinder gaskets and lower intake gasket again. Still engine would not start. After 2 years of car sitting I unplugged maf sensor and then it started finally. Faulty maf sensor but no way to find out unless it is unplugged because sensor did not give off any pertaining fault code pointing to the problem specifically.
