Ok, so my fiance has an 02 Ford explorer, v6, 4x4. It is giving me problems, and I don't know where to start. Hopefully somebody here can point me in the right direction. Here is what is going on: When cold, if you hit the brakes hard, it dies and will not start for a while. Today, the check engine light/oil light/etc went on, and it wanted to keep dying at stop signs/lights. I know the engine is solid, had oil in it, and even started right up 8 hours later and ran/drove absolutely fine. Any help is appreciated.
