Motorcraft meltdown-ignition module!!!
Does anyone know what causes the Motorcraft ignition modules (under the water bottle on drivers side) to go bad and melt?????
My buddies CJ wouldn't run right...I found a huge amount of slack in the chain and replaced it.....at same time I found his module was melted (187K miles)
For the last week, my CJ with 165K miles, started acting funny during acceleration...mainly at around 1500rpms.....like it wasn't getting air, fuel, or the timing was off....once up to speed it runs good, but not perfect .I already bought the seals and chain and have the Jeep all apart now. Lots o' slack on the old chain (is 165K miles on the original chain good?!) And what to I find....my box is melted now...WTF. Is this common? Does high mileage/age wear it out or is it from the timming floating across a large degree span and screws up the box? You can tell a melted box from the wax on the back side is now clear and some has run out down the fender....it still works, just not 100%.
ANY THOUGTS ????
