I'm driving along and all of a sudden my bronco starts running weird. I think nothing of it at the time. The problem keeps up for a few days and then bam, the bronco gets to the point where it will hardly keep the idle. (Almost stranded me) Take it to this shady garage and they tell me its the Fuel pressure regulator. The funny part is the regulator that was currently on it was only about 12,000 miles old and it was a factory replacement part. Got it swapped and have had no problems since then with the regulator.
