    3.0L V6 91 LeBaron/Spirit/Acclaim melted wire insulation under intake

    Anyone familiar with a 1991 3.0L V-6 (single coil and distributor) who knows what this connector goes to from the harness on the back side of the motor under the metal intake box that has the raised 3.0 on it. It connects from the back to something on the center top of the motor.

    This U-Pull-It 91 LeBaron looks like it was well taken care of and used for business as it has a mobile telephone installed, new radiator, sealant on the thermostat housing, new alternator, and sealant squeezed out of the transmission pan gasket. It has 85,000 miles. I pulled all of the air plumbing and battery tray out of the engine compartment.

    What, maybe? did it in is a four wire connector on the back side of the engine that goes under the metal intake box towards the top center of the motor. This connector has the insulation melted and crumbled off of 3 of the 4 wires. (It's not the O2 sensor which is visible)

    I have many 2.5L and 2.2L fours but this is my first V6 adventure.

    That should be the fuel injector connector but you say it only has 4 wires. Can't remember what the non sequential ones look like. Those tend to lose their insulation near the connector on all years and often need some repair to keep bare wires from touching. You can disassemble the connectors and fix them up while everything is apart.
