1988 Jeep Comanche, 4.0, 5 Speed, 2wd. I've had it for a few months, did plugs, wires, cap, rotor, water pump, and some other maintenance when I got it. Its been running good, but had an oil leak, and clutch slave cylinder was going out. So this past week I did pilot bearing, slave, rear main, and oil pan gasket. While it was apart, I noticed the crank position sensor wire was burned up. I cut the burnt a action out and soldered new wire in. I got it all back together last night, and now it has a horrible rough idle. Under load it will smooth out, but at idle its bad. Slow down to come to a stop at a light and it dies sometimes. When idling, it sounds like it has a miss.
