I think my distributor is worn out

When I grab the shaft and rotate, it has about 1* slop. When I wiggle the top of the shaft, it moves about 1/8".

Replace? What say you?

edit: Everything else has been replace at some time or the other...

It misses from time to time. No codes lately. It happens more when the PCM would be adjusting the timing slightly, like changing from a slight grade to flat ground or vice versa. I can make it do it by feathering the pedal. That line of thought is what made me check it.

Doesn't sound bad to me. A little play is normal for the age.

If I were you, I would try it and see if it fixed the problem, if not, you've eliminated one possibility Check your spark plugs and wires too if its missing. Maybe check timing belt too.

It has a chain, not a belt, but i get your drift.

FSM says no more than 1/2" slack, but if I get that far, I'm replacing it...

Has anyone ever had a chain make one skip??

Zee, I;m not getting the 1" slop part. Mine started squealing like a pig on startup about 8 months ago and it turned out to be the bushings. The jeep was still running OK. Side to side play then was about 1/8. Replaced the dist. and all was groovy. Seems like I read somewhere that cardone is now offering "new" distributors. The last time I checked the dealer one was close to 400.

Hmm... got me thinking... (rarity). My ZJ does that at one certain stoplight in my area. There's a really steep downgrade leading up to the stoplight. If I'm on the downgrade and I have to stop for the light, by the end of the light, the ZJ is running like garbage. It doesn't do it every time, but when it does, it's bad. Could that be my distributor? I don't get any codes when it does it and it normally idles a little rough.

That's one degree rotation, not 1 inch. It makes me think that any given time, the timing could off by up to 1 degree

Doesn't sound a lot like a distro... unless you've eliminated a host of other possibilities. I can't say for sure because you're driving a V8 and I'm a 6 banger type.

I've essentially eliminated nothing. I'm going to swap my plugs. The wires and cap are newer (within a year and a half/20,000 miles). I recently did the "zip tie" fix for the connectors on my ECM and that actually seems to have made a slight difference. I wonder if the connections were coming loose and now they're tight. It's probably the placebo affect... Who knows. I also pulled my transmission and fuel pump relays and cleaned the connectors. I figured it wouldn't hurt while I was in there.
