So the roommate ran the fuel low on the 92 XJ, then it started having a surge/rough acceleration problem. It idles fine, but when you apply steady throttle, she wants to surge a bit. Did the fuel filter right away, but that didn't cure it. Fuel pressure is about 30lbs at idle, and up to 40-ish under accel. What is the next place to look at?
