1986 XJ 2.5L. Scanner Uncovers Problems !!! Part 1.

Although this Renix XJ runs pretty good, I thought it was time to put the MT2500 scanner on this rig. I’m concerned that the Map Sensor voltage is low at 1.0 volts. The Long Term Fuel Trims are way too low !! So the fuel system is trying to run the system leaner to make up for something else. Probably the Map Sensor. We shall see !!!
