I have earlier posted a message regarding engine noise
(Subject: Hammering / knocking noise on 4.0L6 '99 Cherokee)
but suspect now more of a electronic problem.
Could the cause of this problem be found
within the electronic / contact / sensor input complex?

Today, no noise at all, so far. No noise at cold start,
no noise during normal driving conditions with a warm
engine. No noise whatsoever.

So, if it would be a purely mechanical problem such as
piston slap, hydraulic lifters, or carbon build up, why is
there no noise today, or why can stopping and restarting
the engine sometimes stop the problem immediately?

I am living in the tropics (Thailand) with a very high humidity
of around 80-90%. Could it be, that somewhere, an electronic
contact or a wrong sensor input causes the engine to produce
this ticking / knocking sounds sometimes?

I believe the problem may involve monkeys.

Have a mechanic do a tune up. Change the plugs, wires, and distributor cap.
