Had an interesting time on a road trip. Tach/speedo would drop to 0, or bounce peg to peg as if possessed by a UFO (lots of 'em in georgia ya know). Engine would suddenly die, only to charge back seconds later (lots of fun with 18 wheelers behind ya), or theft light would flash intermittently. Later, the car would die everytime in reverse (don't go there, have always driven a manual). Anyway, dealer said couldn't replicate, but did inspect every ground wire...so far, no repeat, UFO's off to New Mexico or Ford performed an exorcism I guess.
