When you pull the old plugs note which cyl they are for
and in what condition the ends are. A little grey or
black stuff is fine.

If you haven't done it before, the cap/rotor/wires are also
way past expected lifetime. Also take a look in the
distributor and see if there is any oil down there. Oil
indicates the lower bushing is worn and if the rotor wiggles
at all from side to side then you should get a new distributor.
(cheaper than rebuilding) I did mine a while back.

Re: 96 Grand Cherokee Stalling
 

The saga continues...

I've changed the spark plugs and wires, and added some fuel injector
cleaner. I've checked the fuel pressure at the rail; it's got plenty of
fuel pressure. Nevertheless, sometimes it will just up and stall out on
me. It can be at idle, or at 35 mph. I can even get a quick buck or
hesitation at 50 mph or higher. If I really give it a ton of gas, I
might keep it running, but when I do that it usually sputters, coughs
and chokes, acting like it's running on one or two cylinders. When it
stalls, it rarely wants to start right back up. I have to keep trying
and praying for several minutes. After the last episode, it set five
separate code 43's. Yes, five of them.

I also put in a brand new crankshaft position sensor. Obviously, that
didn't do the trick, even though the old one showed considerably less
than infinite resistance across terminals B and C (suggesting it was
bad).

I guess I'll pull the distributor cap and take a look at the rotor.
Grrr....

Have you replaced the ignition coil?

Re: 96 Grand Cherokee Stalling
 

It doesn't sound like fuel delivery is the problem, especially if it
will not restart immediately. Translate a code 43 for me: it doesn't
sound like the OBD that I am accustomed to.

Regardless of what code it is throwing, basic ignition continuity should
be checked. Intermittant problems are difficult to diagnose and are
labor intensive. Wiggle testing might be your next assignment.
