88 XJ 4.0. was messing around with the distributor today. Replaced a couple of questionable cables.
Noticed the rotor had a lot of play, 1/8-3/16 of an inch at the rotor tip, just gear play, even more if you figure in the lift, if I keep on turning. Maybe itīs normal and I just never noticed before. Seemed awfully sloppy. Pulled the distributor, checked the gear, OK, pin is tight.
Next question, when I put the distributor in and started her up, she idled really nice, then I noticed I didnīt plug, the sync signal sensor plug back up. Idled better with the sensor unpluged? Did I put it in open loop?
Anyway, Iīm making some progress, cleaning the grounds helped (especially the shifts) Resetting the distributor index, was good for a bunch of torque. Idle still hunts some,and it sometimes runs a little rough (unless I unplug the sync signal and ring).
Re-indexing the distributor, quieted down the valve train, used to rattle a bit more.
Think Iīve still got a bug or two in the ignition loop, but itīs close now, idles OK. Still has a little bucking (very little) at a round 2000 RPM.
Any imput would be appreciated. Shop manual isnīt helping much at this stage.
