I hope this post is somewhat on topic. I am the proud owner of a 2000 Focus. I bought it new and it's been great. Driven it coast to coast. I just turned over 75 thou and now it's running poorly. It acts like at low rpm under load while accelerating, it cuts out. Kind of like someone is flicking the on/off switch. If I back off the gas it'll smooth out or if I down shift and get on it, it'll smooth out. Is this a problem that someone has had and already figured out? I'm guessing something fuel related, but it's just a guess.
