why is it that my XJ runs better with the MAP sensor vac. line disconnected than with it hooked up? If you pull the electrical pigtail off, the Jeep dies. Seems normal so far. If you leave the MAP hooked up completely, the motor will back fire, chug, have little power, and so on. I have allready checked the fuel pressure, and it is within spec (I thought that maybe the pump was going out). Any ideas? I am thinking that the membrane in the MAP sensor is popped.
